GMT to PST converter
PST is 7 hours behind GMT right now. UK time (GMT/BST) is the clock in London; Pacific Time is the clock in Los Angeles.
Why the gap changes
London and Los Angeles both observe daylight saving, but the UK switches on the last Sundays of March and October and the US on the second Sunday in March and the first in November. In the weeks between, the gap is an hour smaller than usual.
Over the next 12 months the difference is 7 hours or 8 hours, depending on the date. The table and the converter always use the date you pick. See EST vs EDT for why the abbreviations change.
