Separate out the time, zone, date code from corelib/tools/
We'll be adding calendar code here as well, and tools/ was getting rather crowded, so it looks like time to move out a reasonably coherent sub-bundle of it all. Change-Id: I7e8030f38c31aa307f519dd918a43fc44baa6aa1 Reviewed-by: Lars Knoll <lars.knoll@qt.io>

- \class QDate
- \inmodule QtCore
- \reentrant
- \brief The QDate class provides date functions.
-
-
- A QDate object encodes a calendar date, i.e. year, month, and day numbers,
- in the proleptic Gregorian calendar by default. It can read the current date
- from the system clock. It provides functions for comparing dates, and for
- manipulating dates. For example, it is possible to add and subtract days,
- months, and years to dates.
-
- A QDate object is typically created by giving the year, month, and day
- numbers explicitly. Note that QDate interprets two digit years as presented,
- i.e., as years 0 through 99, without adding any offset. A QDate can also be
- constructed with the static function currentDate(), which creates a QDate
- object containing the system clock's date. An explicit date can also be set
- using setDate(). The fromString() function returns a QDate given a string
- and a date format which is used to interpret the date within the string.
-
- The year(), month(), and day() functions provide access to the
- year, month, and day numbers. Also, dayOfWeek() and dayOfYear()
- functions are provided. The same information is provided in
- textual format by the toString(), shortDayName(), longDayName(),
- shortMonthName(), and longMonthName() functions.
-
- QDate provides a full set of operators to compare two QDate
- objects where smaller means earlier, and larger means later.
-
- You can increment (or decrement) a date by a given number of days
- using addDays(). Similarly you can use addMonths() and addYears().
- The daysTo() function returns the number of days between two
- dates.
-
- The daysInMonth() and daysInYear() functions return how many days
- there are in this date's month and year, respectively. The
- isLeapYear() function indicates whether a date is in a leap year.
-
- \section1 Remarks
-
- \section2 No Year 0
-
- There is no year 0. Dates in that year are considered invalid. The year -1
- is the year "1 before Christ" or "1 before current era." The day before 1
- January 1 CE, QDate(1, 1, 1), is 31 December 1 BCE, QDate(-1, 12, 31).
-
- \section2 Range of Valid Dates
-
- Dates are stored internally as a Julian Day number, an integer count of
- every day in a contiguous range, with 24 November 4714 BCE in the Gregorian
- calendar being Julian Day 0 (1 January 4713 BCE in the Julian calendar).
- As well as being an efficient and accurate way of storing an absolute date,
- it is suitable for converting a Date into other calendar systems such as
- Hebrew, Islamic or Chinese. The Julian Day number can be obtained using
- QDate::toJulianDay() and can be set using QDate::fromJulianDay().
-
- The range of dates able to be stored by QDate as a Julian Day number is
- for technical reasons limited to between -784350574879 and 784354017364,
- which means from before 2 billion BCE to after 2 billion CE.

- \class QTime
- \inmodule QtCore
- \reentrant
-
- \brief The QTime class provides clock time functions.
-
-
- A QTime object contains a clock time, which it can express as the numbers of
- hours, minutes, seconds, and milliseconds since midnight. It provides
- functions for comparing times and for manipulating a time by adding a number
- of milliseconds.
-
- QTime uses the 24-hour clock format; it has no concept of AM/PM.
- Unlike QDateTime, QTime knows nothing about time zones or
- daylight-saving time (DST).
-
- A QTime object is typically created either by giving the number
- of hours, minutes, seconds, and milliseconds explicitly, or by
- using the static function currentTime(), which creates a QTime
- object that contains the system's local time. Note that the
- accuracy depends on the accuracy of the underlying operating
- system; not all systems provide 1-millisecond accuracy.
-
- The hour(), minute(), second(), and msec() functions provide
- access to the number of hours, minutes, seconds, and milliseconds
- of the time. The same information is provided in textual format by
- the toString() function.
-
- The addSecs() and addMSecs() functions provide the time a given
- number of seconds or milliseconds later than a given time.
- Correspondingly, the number of seconds or milliseconds
- between two times can be found using secsTo() or msecsTo().
-
- QTime provides a full set of operators to compare two QTime
- objects; an earlier time is considered smaller than a later one;
- if A.msecsTo(B) is positive, then A < B.

-/*!
- \class QDateTime
- \inmodule QtCore
- \ingroup shared
- \reentrant
- \brief The QDateTime class provides date and time functions.
-
-
- A QDateTime object encodes a calendar date and a clock time (a
- "datetime"). It combines features of the QDate and QTime classes.
- It can read the current datetime from the system clock. It
- provides functions for comparing datetimes and for manipulating a
- datetime by adding a number of seconds, days, months, or years.
-
- A QDateTime object is typically created either by giving a date
- and time explicitly in the constructor, or by using the static
- function currentDateTime() that returns a QDateTime object set
- to the system clock's time. The date and time can be changed with
- setDate() and setTime(). A datetime can also be set using the
- setTime_t() function that takes a POSIX-standard "number of
- seconds since 00:00:00 on January 1, 1970" value. The fromString()
- function returns a QDateTime, given a string and a date format
- used to interpret the date within the string.
-
- The date() and time() functions provide access to the date and
- time parts of the datetime. The same information is provided in
- textual format by the toString() function.
-
- QDateTime provides a full set of operators to compare two
- QDateTime objects, where smaller means earlier and larger means
- later.
-
- You can increment (or decrement) a datetime by a given number of
- milliseconds using addMSecs(), seconds using addSecs(), or days
- using addDays(). Similarly, you can use addMonths() and addYears().
- The daysTo() function returns the number of days between two datetimes,
- secsTo() returns the number of seconds between two datetimes, and
- msecsTo() returns the number of milliseconds between two datetimes.
-
- QDateTime can store datetimes as \l{Qt::LocalTime}{local time} or
- as \l{Qt::UTC}{UTC}. QDateTime::currentDateTime() returns a
- QDateTime expressed as local time; use toUTC() to convert it to
- UTC. You can also use timeSpec() to find out if a QDateTime
- object stores a UTC time or a local time. Operations such as
- addSecs() and secsTo() are aware of daylight-saving time (DST).
-
- \note QDateTime does not account for leap seconds.
-
- \section1 Remarks
-
- \section2 No Year 0
-
- There is no year 0. Dates in that year are considered invalid. The
- year -1 is the year "1 before Christ" or "1 before current era."
- The day before 1 January 1 CE is 31 December 1 BCE.
-
- \section2 Range of Valid Dates
-
- The range of valid values able to be stored in QDateTime is dependent on
- the internal storage implementation. QDateTime is currently stored in a
- qint64 as a serial msecs value encoding the date and time. This restricts
- the date range to about +/- 292 million years, compared to the QDate range
- of +/- 2 billion years. Care must be taken when creating a QDateTime with
- extreme values that you do not overflow the storage. The exact range of
- supported values varies depending on the Qt::TimeSpec and time zone.
-
- \section2 Use of System Timezone
-
- QDateTime uses the system's time zone information to determine the
- offset of local time from UTC. If the system is not configured
- correctly or not up-to-date, QDateTime will give wrong results as
- well.
-
- \section2 Daylight-Saving Time (DST)
-
- QDateTime takes into account the system's time zone information
- when dealing with DST. On modern Unix systems, this means it
- applies the correct historical DST data whenever possible. On
- Windows, where the system doesn't support historical DST data,
- historical accuracy is not maintained with respect to DST.
-
- The range of valid dates taking DST into account is 1970-01-01 to
- the present, and rules are in place for handling DST correctly
- until 2037-12-31, but these could change. For dates falling
- outside that range, QDateTime makes a \e{best guess} using the
- rules for year 1970 or 2037, but we can't guarantee accuracy. This
- means QDateTime doesn't take into account changes in a locale's
- time zone before 1970, even if the system's time zone database
- supports that information.
-
- QDateTime takes into consideration the Standard Time to Daylight-Saving Time
- transition. For example if the transition is at 2am and the clock goes
- forward to 3am, then there is a "missing" hour from 02:00:00 to 02:59:59.999
- which QDateTime considers to be invalid. Any date maths performed
- will take this missing hour into account and return a valid result.
-
- \section2 Offset From UTC
-
- A Qt::TimeSpec of Qt::OffsetFromUTC is also supported. This allows you
- to define a QDateTime relative to UTC at a fixed offset of a given number
- of seconds from UTC. For example, an offset of +3600 seconds is one hour
- ahead of UTC and is usually written in ISO standard notation as
- "UTC+01:00". Daylight-Saving Time never applies with this TimeSpec.
-
- There is no explicit size restriction to the offset seconds, but there is
- an implicit limit imposed when using the toString() and fromString()
- methods which use a format of [+|-]hh:mm, effectively limiting the range
- to +/- 99 hours and 59 minutes and whole minutes only. Note that currently
- no time zone lies outside the range of +/- 14 hours.
-
- \section2 Time Zone Support
-
- A Qt::TimeSpec of Qt::TimeZone is also supported in conjunction with the
- QTimeZone class. This allows you to define a datetime in a named time zone
- adhering to a consistent set of daylight-saving transition rules. For
- example a time zone of "Europe/Berlin" will apply the daylight-saving
- rules as used in Germany since 1970. Note that the transition rules
- applied depend on the platform support. See the QTimeZone documentation
- for more details.

- Returns the QDateTime represented by the \a string, using the \a
- format given, or an invalid datetime if the string cannot be parsed.
-
- These expressions may be used for the date part of the format string:
-
- \table
- \header \li Expression \li Output
- \row \li d \li the day as number without a leading zero (1 to 31)
- \row \li dd \li the day as number with a leading zero (01 to 31)
- \row \li ddd
- \li the abbreviated localized day name (e.g. 'Mon' to 'Sun').
- Uses QDate::shortDayName().
- \row \li dddd
- \li the long localized day name (e.g. 'Monday' to 'Sunday').
- Uses QDate::longDayName().
- \row \li M \li the month as number without a leading zero (1-12)
- \row \li MM \li the month as number with a leading zero (01-12)
- \row \li MMM
- \li the abbreviated localized month name (e.g. 'Jan' to 'Dec').
- Uses QDate::shortMonthName().
- \row \li MMMM
- \li the long localized month name (e.g. 'January' to 'December').
- Uses QDate::longMonthName().
- \row \li yy \li the year as two digit number (00-99)
- \row \li yyyy \li the year as four digit number
- \endtable
-
- \note Unlike the other version of this function, day and month names must
- be given in the user's local language. It is only possible to use the English
- names if the user's language is English.
-
- These expressions may be used for the time part of the format string:
-
- \table
- \header \li Expression \li Output
- \row \li h
- \li the hour without a leading zero (0 to 23 or 1 to 12 if AM/PM display)
- \row \li hh
- \li the hour with a leading zero (00 to 23 or 01 to 12 if AM/PM display)
- \row \li H
- \li the hour without a leading zero (0 to 23, even with AM/PM display)
- \row \li HH
- \li the hour with a leading zero (00 to 23, even with AM/PM display)
- \row \li m \li the minute without a leading zero (0 to 59)
- \row \li mm \li the minute with a leading zero (00 to 59)
- \row \li s \li the whole second without a leading zero (0 to 59)
- \row \li ss \li the whole second with a leading zero where applicable (00 to 59)
- \row \li z \li the fractional part of the second, to go after a decimal
- point, without trailing zeroes (0 to 999). Thus "\c{s.z}"
- reports the seconds to full available (millisecond) precision
- without trailing zeroes.
- \row \li zzz \li the fractional part of the second, to millisecond
- precision, including trailing zeroes where applicable (000 to 999).
- \row \li AP or A
- \li interpret as an AM/PM time. \e AP must be either "AM" or "PM".
- \row \li ap or a
- \li Interpret as an AM/PM time. \e ap must be either "am" or "pm".
- \endtable
-
- All other input characters will be treated as text. Any sequence
- of characters that are enclosed in single quotes will also be
- treated as text and not be used as an expression.
-
- \snippet code/src_corelib_tools_qdatetime.cpp 12
-
- If the format is not satisfied, an invalid QDateTime is returned.
- The expressions that don't have leading zeroes (d, M, h, m, s, z) will be
- greedy. This means that they will use two digits even if this will
- put them outside the range and/or leave too few digits for other
- sections.
-
- \snippet code/src_corelib_tools_qdatetime.cpp 13
-
- This could have meant 1 January 00:30.00 but the M will grab
- two digits.
-
- Incorrectly specified fields of the \a string will cause an invalid
- QDateTime to be returned. For example, consider the following code,
- where the two digit year 12 is read as 1912 (see the table below for all
- field defaults); the resulting datetime is invalid because 23 April 1912
- was a Tuesday, not a Monday:
-
- \snippet code/src_corelib_tools_qdatetime.cpp 20
-
- The correct code is:
-
- \snippet code/src_corelib_tools_qdatetime.cpp 21
-
- For any field that is not represented in the format, the following
- defaults are used:
-
- \table
- \header \li Field \li Default value
- \row \li Year \li 1900
- \row \li Month \li 1 (January)
- \row \li Day \li 1
- \row \li Hour \li 0
- \row \li Minute \li 0
- \row \li Second \li 0

- \class QTimeZone
- \inmodule QtCore
- \since 5.2
-
- \brief The QTimeZone class converts between UTC and local time in a specific
- time zone.
-
- \threadsafe
-
- This class provides a stateless calculator for time zone conversions
- between UTC and the local time in a specific time zone. By default it uses
- the host system time zone data to perform these conversions.
-
- This class is primarily designed for use in QDateTime; most applications
- will not need to access this class directly and should instead use
- QDateTime with a Qt::TimeSpec of Qt::TimeZone.
-
- \note For consistency with QDateTime, QTimeZone does not account for leap
- seconds.
-
- \section1 Remarks
-
- \section2 IANA Time Zone IDs
-
- QTimeZone uses the IANA time zone IDs as defined in the IANA Time Zone
- Database (http://www.iana.org/time-zones). This is to ensure a standard ID
- across all supported platforms. Most platforms support the IANA IDs
- and the IANA Database natively, but for Windows a mapping is required to
- the native IDs. See below for more details.
-
- The IANA IDs can and do change on a regular basis, and can vary depending
- on how recently the host system data was updated. As such you cannot rely
- on any given ID existing on any host system. You must use
- availableTimeZoneIds() to determine what IANA IDs are available.
-
- The IANA IDs and database are also know as the Olson IDs and database,
- named after their creator.
-
- \section2 UTC Offset Time Zones
-
- A default UTC time zone backend is provided which is always guaranteed to
- be available. This provides a set of generic Offset From UTC time zones
- in the range UTC-14:00 to UTC+14:00. These time zones can be created
- using either the standard ISO format names "UTC+00:00" as listed by
- availableTimeZoneIds(), or using the number of offset seconds.
-
- \section2 Windows Time Zones
-
- Windows native time zone support is severely limited compared to the
- standard IANA TZ Database. Windows time zones cover larger geographic
- areas and are thus less accurate in their conversions. They also do not
- support as much historic conversion data and so may only be accurate for
- the current year.
-
- QTimeZone uses a conversion table derived form the Unicode CLDR data to map
- between IANA IDs and Windows IDs. Depending on your version of Windows
- and Qt, this table may not be able to provide a valid conversion, in which
- "UTC" will be returned.
-
- QTimeZone provides a public API to use this conversion table. The Windows ID
- used is the Windows Registry Key for the time zone which is also the MS
- Exchange EWS ID as well, but is different to the Time Zone Name (TZID) and
- COD code used by MS Exchange in versions before 2007.
-
- \section2 System Time Zone
-
- QTimeZone does not support any concept of a system or default time zone.
- If you require a QDateTime that uses the current system time zone at any
- given moment then you should use a Qt::TimeSpec of Qt::LocalTime.
-
- The method systemTimeZoneId() returns the current system IANA time zone
- ID which on Unix-like systems will always be correct. On Windows this ID is
- translated from the Windows system ID using an internal translation
- table and the user's selected country. As a consequence there is a small
- chance any Windows install may have IDs not known by Qt, in which case
- "UTC" will be returned.
-
- Creating a new QTimeZone instance using the system time zone ID will only
- produce a fixed named copy of the time zone, it will not change if the
- system time zone changes.
-
- \section2 Time Zone Offsets
-
- The difference between UTC and the local time in a time zone is expressed
- as an offset in seconds from UTC, i.e. the number of seconds to add to UTC
- to obtain the local time. The total offset is comprised of two component
- parts, the standard time offset and the daylight-saving time offset. The
- standard time offset is the number of seconds to add to UTC to obtain
- standard time in the time zone. The daylight-saving time offset is the
- number of seconds to add to the standard time offset to obtain
- daylight-saving time (abbreviated DST and sometimes called "daylight time"
- or "summer time") in the time zone.
-
- Note that the standard and DST offsets for a time zone may change over time
- as countries have changed DST laws or even their standard time offset.
-
- \section2 License
-
- This class includes data obtained from the CLDR data files under the terms
- of the Unicode Data Files and Software License. See
- \l{Unicode Common Locale Data Repository (CLDR)} for details.

- Offsets are Local - UTC, positive to the east of Greenwich, negative to

-
- Non-DST transitions (jurisdictions changing time-zone and time-zones
- changing their standard offset, typically) are described below as if they
- were DST transitions (since these are more usual and familiar); the code
- mostly concerns itself with offsets from UTC, described in terms of the
- common case for changes in that. If there is no actual change in offset
- (e.g. a DST transition cancelled by a standard offset change), this code
- should handle it gracefully; without transitions, it'll see early == late
- and take the easy path; with transitions, tran and nextTran get the
- correct UTC time as atMSecsSinceEpoch so comparing to nextStart selects
- the right one. In all other cases, the transition changes offset and the
- reasoning that applies to DST applies just the same. Aside from hinting,
- the only thing that looks at DST-ness at all, other than inferred from
- offset changes, is the case without transition data handling an invalid
- time in the gap that a transition passed over.
-
- The handling of hint (see below) is apt to go wrong in non-DST
- transitions. There isn't really a great deal we can hope to do about that
- without adding yet more unreliable complexity to the heuristics in use for
- already obscure corner-cases.

- The hint (really a QDateTimePrivate::DaylightStatus) is > 0 if caller
- thinks we're in DST, 0 if in standard. A value of -2 means never-DST, so
- should have been handled above; if it slips through, it's wrong but we
- should probably treat it as standard anyway (never-DST means
- always-standard, after all). If the hint turns out to be wrong, fall back
- on trying the other possibility: which makes it harmless to treat -1
- (meaning unknown) as standard (i.e. try standard first, then try DST). In
- practice, away from a transition, the only difference hint makes is to
- which candidate we try first: if the hint is wrong (or unknown and
- standard fails), we'll try the other candidate and it'll work.
-
- For the obscure (and invalid) case where forLocalMSecs falls in a
- spring-forward's missing hour, a common case is that we started with a
- date/time for which the hint was valid and adjusted it naively; for that
- case, we should correct the adjustment by shunting across the transition
- into where hint is wrong. So half-way through the gap, arrived at from
- the DST side, should be read as an hour earlier, in standard time; but, if
- arrived at from the standard side, should be read as an hour later, in
- DST. (This shall be wrong in some cases; for example, when a country
- changes its transition dates and changing a date/time by more than six
- months lands it on a transition. However, these cases are even more
- obscure than those where the heuristic is good.)

- Main rules for defining TZ/IANA names as per ftp://ftp.iana.org/tz/code/Theory
- 1. Use only valid POSIX file name components
- 2. Within a file name component, use only ASCII letters, `.', `-' and `_'.
- 3. Do not use digits (except in a [+-]\d+ suffix, when used).
- 4. A file name component must not exceed 14 characters or start with `-'
- However, the rules are really guidelines - a later one says
- - Do not change established names if they only marginally violate the
- above rules.
- We may, therefore, need to be a bit slack in our check here, if we hit
- legitimate exceptions in real time-zone databases.
-
- In particular, aliases such as "Etc/GMT+7" and "SystemV/EST5EDT" are valid
- so we need to accept digits, ':', and '+'; aliases typically have the form
- of POSIX TZ strings, which allow a suffix to a proper IANA name. A POSIX
- suffix starts with an offset (as in GMT+7) and may continue with another
- name (as in EST5EDT, giving the DST name of the zone); a further offset is
- allowed (for DST). The ("hard to describe and [...] error-prone in
- practice") POSIX form even allows a suffix giving the dates (and
- optionally times) of the annual DST transitions. Hopefully, no TZ aliases
- go that far, but we at least need to accept an offset and (single
- fragment) DST-name.
-
- But for the legacy complications, the following would be preferable if
- QRegExp would work on QByteArrays directly:
- const QRegExp rx(QStringLiteral("[a-z+._][a-z+._-]{,13}"
- "(?:/[a-z+._][a-z+._-]{,13})*"
- // Optional suffix:
- "(?:[+-]?\d{1,2}(?::\d{1,2}){,2}" // offset
- // one name fragment (DST):
- "(?:[a-z+._][a-z+._-]{,13})?)"),
- Qt::CaseInsensitive);

- support them., e.g. Mac does not support availableTimeZones() filtering by region or offset.
-
- Another data table is provided for generic UTC+00:00 format time zones to be used as a
- fall-back if no system time zones are available (QT_NO_SYSTEMLOCALE is set) or for QDateTimes
- with a QT:Spec of OffsetFromUTC
-
- These tables are automatically adapted from the CLDR supplemental/windowsZones.xml data file
- using a script in qtbase/util/locale_database. Please do not edit this data directly. In the
- future if ICU is made a hard dependency then the ICU resource can be used directly and this

- Check for potential "fake DST", used by MS's APIs because the

- year, or expresses a transition of each kind, even if standard time
- did change in a year with no DST. We've seen year-start fake-DST
- (whose offset matches prior standard offset, in which the previous
- year ended); and conjecture that similar might be used at a year-end.
- (This might be used for a southern-hemisphere zone, where the start of
- the year usually is in DST, when applicable.) Note that, here, wDay
- identifies an instance of a given day-of-week in the month, with 5
- meaning last.
-
- Either the alleged standardTimeRule or the alleged daylightTimeRule
- may be faked; either way, the transition is actually a change to the
- current standard offset; but the unfaked half of the rule contains the
- useful bias data, so we have to go along with its lies.
-
- Example: Russia/Moscow
- Format: -bias +( -stdBias, stdDate | -dstBias, dstDate ) notes
- Last year of DST, 2010: 180 +( 0, 0-10-5 3:0 | 60, 0-3-5 2:0 ) normal DST
- Zone change in 2011: 180 +( 0, 0-1-1 0:0 | 60 0-3-5 2:0 ) fake DST at transition
- Fixed standard in 2012: 240 +( 0, 0-0-0 0:0 | 60, 0-0-0 0:0 ) standard time years
- Zone change in 2014: 180 +( 0, 0-10-5 2:0 | 60, 0-1-1 0:0 ) fake DST at year-start
- The last of these is missing on Win7 VMs (too old to know about it).
