The code made two incorrect assumptions: that the strings used are "AM"
or "PM", or would be translated. Instead, the locale provides the
correct strings, and there is no need to translate. However, in order
not to break existing translations, we give those preference.
And that the AM/PM string is not longer than 4 characters, while in
e.g Spanish/Columbia locale the strings are "A. M." and "P. M.", ie 5
characters long. Also, the use of qMin in a function that is asked to
provide the maximum section length is wrong.
[ChangeLog][QWidgets][QDateTimeEdit] Use the information provided by
the locale to determine the AM/PM strings, unless they are already
translated.

Constructing a QStringRef directly from the string, offset and a

The operator_eqeq(data13) test expected the local-time epoch and UTC
epoch to agree precisely if the localTimeType set by the test's
constructor says local time is UTC; however, when the local zone is
*sometimes* ahead of (or behind) UTC, due to DST, localTimeType is
duly set to indicate that, which doesn't preclude the zone agreeing
with UTC at the epoch. This indeed happens for Europe/London, which
agrees on the epoch but was ahead a few months later. So we can't
determine what outcome to expect based solely on localTimeType,
although we can be sure of a match when local time is UTC. So skip

The example from QTBUG-59061 caused this because toUTC() -> toTimeSpec()
calls setMSecsSinceEpoch which left the bit set; then addDays() calls
setDateTime(), which calls checkValidDateTime() and that corrupted the
pointer. This problem was more visible on 32-bit systems because no

Some format and parse tests for time and date-time depended on locale

The date-time test did *some* attempts at fixing for locale, but

Q(Date|Time)+::fromString indicating that we intend to switch these

QDateTimeParser uses systemLocale(), which is initialized the first

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).
