This is useful when sorting by time and using QTimeZone::UTC, since
native filesystem API uses UTC, that means less conversions, which is
potentially faster.
Use UTC internally except for strings that are going to be shown in a
GUI to the user, these should be in QTimeZone::LocalTime.
[ChangeLog][QtGui][QFileSystemModel] Added lastModified() overload that
takes a QTimeZone, this is useful when e.g. comparing file timestamps
and all that's needed is time in UTC (this is faster as no time zone
conversions is required). QTimeZone::UTC is used internally when sorting
by time (using the sort() function), which should ideally make it
faster too.
