GST to PST time conversion
The difference between GST and PST is fixed: PST is 12 hours behind GST. For example, 9:00 AM (09:00) GST is 21:00 PST, and 6:00 PM (18:00) GST is 06:00 PST. The chart above lists the conversion for every hour of the day.
These conversions use each zone's standard UTC offset — UTC+04:00 for GST (Gulf Standard Time) and UTC−08:00 for PST (Pacific Standard Time) — so the result is exact and does not shift with Daylight Saving Time. To convert a real calendar date between cities with automatic DST handling, use the full time zone converter.
