newOffset
Creates a #GTimeZone corresponding to the given constant offset from UTC, in seconds.
This is equivalent to calling g_time_zone_new() with a string in the form [+|-]hh[:mm[:ss]].
It is possible for this function to fail if @seconds is too big (greater than 24 hours), in which case this function will return the UTC timezone for backwards compatibility. To detect failures like this, use g_time_zone_new_identifier() directly.
Return
a timezone at the given offset from UTC, or UTC on failure
