About these two clocks
GMT — Greenwich Mean Time. Used in UTC+0; the UK uses it in winter only. GMT itself never shifts. The UK leaves GMT for BST (UTC+1) from late March to late October, so “London time” and GMT differ in summer.
PST — Pacific Time. Used in Los Angeles, San Francisco, Seattle, Vancouver. PST is the winter name; from March to November the same clocks show PDT (UTC−7).
All figures on this page come from the IANA time zone database (the same data your phone and laptop use), evaluated for the date in question. Abbreviations are ambiguous — “IST” also means Irish or Israel Standard Time, and “CST” is China Standard Time in Asia — so this page uses Etc/GMT and America/Los_Angeles explicitly.
