* QTimeZonePrivate: make clone() const, use covariant return typesMarc Mutz2017-02-231-1/+1
| | | | | | | | | | | | There's nothing wrong with cloning a const QTimeZonePrivate, so make clone() const. Also, if you're cloning a QTzTimeZonePrivate, you already know that you get a QTzTimeZonePrivate back. C++ supports covariant return types for this reason, so use them.

* QDateTime, QTimeZone: fix mappings from zone time to UTCEdward Welbourne2016-12-121-52/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Such mappings are ill-defined in the presence of daylight-savings time (DST); at its transitions, you need information about whether DST is active or not to determine the correct UTC value. Existing code did not have a way to be told that hint, so could not be correct. Fixing this required changing the (thankfully private) APIs by which QDateTime accessed QTimeZone's information stipulated by zone time. In QDateTime, this required propagating the needed hint, when DST status was known. QAndroidTimeZonePrivate overloaded QTimeZonePrivate::dataForLocalTime with an implementation that works whenever !hasTransitions(); the base implementation handled this case lamely, so I've moved the Android implementation there, to have only one place for both re-writes. Amended tst_QDateTime's expected failures; passing a date and time to the constructor *is* ambiguous when the moment indicated is in a transition. I have changed which way we resolve that ambiguity. Added round-trip test of QDateTime's fromMSecs/toMSecs (but as a QTimeZone test, since that's what's actually getting tested), based on a test-case from Marko Kangas. Initially failed for various zones, each at one hour-offset; and, on some platforms, for some zones, at all offsets. These last revealed that a platform may claim to have zone information yet, for some zones, lack it (or have very incomplete information). In each case, despite this, the platform does give offsetFromUtc(). (The test also found another pre-existing bug on Linux; fixed in an earlier commit.) To accommodate these gaps in transition data, the transition-based code now falls back to the offsetFromUtc()-based code (used when there are no transitions) if it can't find a previous transition (which, in any case, it needs to do its job).

* Prefer "daylight-saving time" and "DST" over "daylight time".Edward Welbourne2015-11-121-11/+11
| | | | | | | | | | | The first two are the "proper" terms; the last is a colloquialism. Also amended "daylight savings" (which summons to mind a hybrid of "daylight robbery" and "bargain-basket savings"). Improved related wording in many of the places amended.

* Update copyright headersJani Heikkinen2015-02-111-6/+6
| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <>
* fix daylight time in QTimeZone on AndroidDrew Parsons2014-12-111-0/+52
| | | | | | | | | | | | | | Android does not provide an API to access daylight time transitions, so the standard QTimeZonePrivate::dataForLocalTime only returns standard time without the daylight offset Therefore provide an override, QAndroidTimeZonePrivate::dataForLocalTime, which tests daylight time offsets directly rather than using transitions.

* provide Android timezones in QTimeZoneDrew Parsons2014-11-261-0/+235
QTimeZone on a unix-based system expects IANA (Olson) timezones to be provided in /usr/share/zoneinfo or /usr/lib/zoneinfo. But on an Android system the timezone datafiles at this location are incomplete (Android instead uses the java class java.util.TimeZone). QTimeZone on Android therefore would only return the default UTC timezones, not the full set of IANA timezones. This patch invokes JNI on an Android system to make the full set of java timezones known to QTimeZone. The implementation adds a new QAndroidTimeZonePrivate class, invoked by the private implementation of QTimeZone in place of QTzTimeZonePrivate. QAndroidTimeZonePrivate contains adds a new QJNIObjectPrivate [java.util.TimeZone] androidTimeZone property which is used to access the java timezone API. Android limitations: 1) the java class java.util.TimeZone does not provide transitions (see 2) abbreviation( ) is provided using Java TimeZone::getDisplayName( ) with the java SHORT style. This sometimes generates a GMT reference instead of a three-letter code, e.g. America/Sao_Paulo returns "GMT-03:00" instead of "BRT" 3) hasDaylightTime() is handled using Java TimeZone::useDaylightTime(), which according to java (Android) documentation only tests for future transitions, not past transitions. This might conflict with the Qt documentation for this function (which is intended to test also for past transitions).
