What is the difference in time GMT vs. PST?
GMT (Greenwich Mean Time) is the time determined by the sun’s highest position in the sky, over Greenwich London, UK. This Longitudinal line is perpendicular to the Equator by 90 degrees. PST stands for Pacific Standard Time, one of 11 time zones that span North America (thought there were only 4, huh?). It mainly covers the West coast and includes the states of Washington and California. There is a difference of 7 hours between GMT and PST.
