Greenwich Mean Time (GMT) is based on the Europe/London IANA timezone. DST observance depends on the jurisdiction — for example, most of the continental US switches between standard and daylight time, while India, Japan, and most of Southeast Asia do not observe DST at all. WorldClock.lol uses the authoritative IANA timezone database, so every conversion automatically accounts for the correct DST rules on the date you're converting.
When it is 9:00 AM in Greenwich Mean Time (GMT, UTC+0), it is 1:00 AM in Pacific Standard Time (PST). For other times of day, scan the conversion table above or drop into the interactive converter to pick an exact minute. The converter handles both standard and daylight variants correctly.
