At the Daylight Tme to Standard Time transition, the local time repeats
itself, i.e. 2am occurs twice. Qt's behavior when setting this using
the local time is ambiguous, as it depends on the system implementation
of mktime, which behaves differently on different platforms. Currently
this behavior remains undefined. When setting using an msecs or time_t
value however we can determine the correct instance to use and cache it
to ensure that any conversion back from local time to msecs is performed
consistantly on all platforms.
Note that caching this value will result in any calculations being wrong
should the system time zone change, or its rules change. This will be
fixed in Qt 5.3 when the system time zone change signal is implemented
and QDateTime switches to using QTimeZone instead of mktime to provide
consistnt behavior across platforms.
The QTimeZone spec does not require this fix as it already caches the
correct offset in setMSecsFromEpoch().

Mac uses the CLDR format codes which need to be translated into their
Qt equivalent. The existing code mistranslates the year code, is
outdated for a number of new codes introduced in recent versions of
CLDR, and by default accepted any codes it didn't recognize.
This change updates support to the latest version of CLDR, fixes the
treatment of years, and defaults to ignoring any new format codes
added in the future.
Note that this change cannot have auto tests written as the system
locale formats change between versions of OSX. Testing must be
done manually by changing system locale and formats.

Implement the new QTimeZone class based on the Olsen Time Zone ID's.
This is the base implementation and does not include the Platform
backends which are implemented separately.
This change does include a default UTC backed to be used if no Platform
backend is available, i.e. if QT_NO_SYSTEMLOCALE is set and ICU is not
configured. This backend also provides a default set of time zones in
the standard "UTC+00:00" offset format that are guaranteed to always
exist regardless of the Platform backend.
This change includes conversion functions between the Olsen ID's and
Windows ID's using a conversion table based on Unicode CLDR data.
This is implemented for all platforms for scenarios such as a Linux
program needing to communicate with a Windows Exchange Server using
the Windows ID.

When Daylight Time transtion goes from Standard Time to Daylight Time
there is a "missing" hour, i.e. at 2am CET the clock goes forward to
3am. Currently QDateTime ignores this gap and considers the time to be
valid and able to be manipulated. This change respects the transition,
so any time set in the missing hour is considered invalid, and any date
maths returns valid results.
The validity in the current time zone needs to be checked every time
isValid() is called in case the system time zone has changed since the
last time it was checked. This is done by calling mktime to check the
returned result matches the expected result. This could be very
inefficient, but the returned offset value is cached each time so
mktime is not required to be called again within each method call,
effectively meaning mktime is called the same number of times by
each method. Note that this means any new methods added must be
careful to ensure either isValid() or refreshLocalTime() is called
first by any method needing to use the UTC value.
[ChangeLog][QtCore][QDateTime] The Standard Time to Daylight Time
transition for Qt::LocalTime is now handled correctly. Any date set
in the "missing" hour is now considered invalid. All date math results
that fall into the missing hour will be automatically adjusted to a
valid time in the following hour.

Change from storing the date and time as QDate and QTime to a serialised
msecs format. This format is a direct translation of the QDate and
QTime values, it is not the actual msecs since the Unix epoch. This
msecs format ensures we are always able to recreate the original QDate
and QTime values, but should still simplify the code and improve
performance.
Because we no longer store the explicit date and time we need to store
their isNull()/isValid() status separately.
The changes in storage results in the same memory footprint as before.
Note that this change does not optimize the code nor set out to fix the
known bugs, it only seeks to maintain the current behavior, although
some bugs are fixed implicitly. More bug fixes and optimizations will
follow.
[ChangeLog][Important Behavior Changes] The supported date range in

A number of QDateTime functions directly use or modify the data stored
in the private, but future changes to store msecs and status make this
maintenance more complicated. Where possible simplify this code to use
the standard msecs functions, standard constructors, or public api
instead. This greatly simplifies the functions and the following msecs
storage code changes.
This is an intermim step towards storing the time in msecs. Some
functions will be slower as a result of this change, optimization
will take place after all the msecs changes are completed.
Note this also removes a test that used valid QDates outside the range
of msecs, this change in behavior will be documented in the final

QMap explicitly sorts its entries by key value. For an ordered container
it's (often?) useful to access the first or last entry, for instance to
quickly compute the next key of the mapping. The first entry is easily
accessible by the STL begin() method, but for accessing the last entry
pretty ugly iterator arithmetics must be applied: *(end() - 1). With
their first() and last() accessors the container classes QList and
QVector provide a much nicer method of accessing extrema, so for
consistency this syntactical sugar also should be applied to QMap.
