Scheduling between GMT and PST
With 8 hours between them there is little or no overlap in normal working hours; one side will be early morning or evening. 8 AM GMT is 12:00 AM PST, and 6 PM GMT is 10:00 AM PST. Always write the city alongside the abbreviation in invites — several abbreviations (CST, IST, AST) are used by more than one region.
