"""Data relating to timezones and CLDR.
This is not implicated in public APIs, so may safely be changed.
Contrast the enumdata.py, where public API is implicated.
Scripts digesting CLDR data shall report the updates you need to make,
if any arise.
The windowsIdList is a list of twoples (ID, offset), associating each
Windows-specific ID for a zone with that zone's offset from UTC, in
seconds. Entries are sorted in case-insensitive lexical order by
ID. If a script reports that it has found a Windows ID not listed
here, research the relevant zone's offset and add a new entry to the
list of twoples, preserving the ordering. Internet search engines and
timeanddate.com can help with researching the offset. Note that some
UTC offset zones (giving only the hour) are present in windowsIdList.
The utcIdList is again a list of tuples (name, offset), associating
various UTC-offset names with their offsets in seconds. Aside from
'UTC' itself, shared with windowsIdList, these include minutes in
their offsets even when they are whole hour offsets. It is not clear
where this particular list of offsets came from, but entries should
not be removed as they make up the available zones of the UTC
back-end. (That recognizes other offset zones, and its is-available
check will accept them, but it leaves them out of its list. There are,
after all, thousands of possible offset zones, but relatively few are
widely used.)
Note: -00:00 (without the UTC prefix) was introduced in RFC3339 as a
way to indicate that a date-time has been converted to UTC but its use
should not be understood to say anything about the local time of the
origin of the message using it. However, ISO 8601 has, since 2000,
forbidden this as an offset suffix. The more recent compromise is to
use Z to convey the meaning RFC3339 gave to -00:00. So the use of
-00:00 as offset suffix should be avoided (and, by extension, likewise
for UTC-00:00 as a zone ID), but this suffix (and ID) should be
recognized when consuming data generated by other sources, for
backwards compatibility.
