QDateTime - Extend fromMSecsSinceEpoch API
Add convenience methods for fromMSecsSinceEpoch() and
fromTime_t() to enable direct creation of other time specs
than LocalTime without the overhead of unncessary conversions.
For example instead of:
QDateTime dt = fromMSecsSinceEpoch(12345).toUtc();
the following saves two conversions:
QDateTime dt = fromMSecsSinceEpoch(12345, Qt:UTC);
This will improve the performance of the new QTimeZone class.
[ChangeLog][QtCore][QDateTime] Added convenience methods for
fromMSecsSinceEpoch() and fromTime_t() to take time spec to be used in
returned datetime.
