getIdentifier
Get the identifier of this #GTimeZone, as passed to g_time_zone_new(). If the identifier passed at construction time was not recognised, UTC
will be returned. If it was null, the identifier of the local timezone at construction time will be returned.
The identifier will be returned in the same format as provided at construction time: if provided as a time offset, that will be returned by this function.
