The TIME WITH TIME ZONE data type is a variant of TIME that includes a time zone displacement in its value. The time zone displacement is the difference (in hours and minutes) between local time and UTC (coordinated universal time, formerly Greenwich mean time). It is specified as follows:

TIME [(fractional_second_precision)] WITH [LOCAL] TIME ZONE

If the LOCAL option is specified, then data stored in the database is normalized to the database time zone, and time zone displacement is not stored as part of the column data. When the data is retrieved, it is returned in the user's local session time zone.
