About these two clocks

UTC — Coordinated Universal Time. Used in the world reference clock used by servers, aviation and logs. UTC never changes for daylight saving time.

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.

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 UTC and Etc/GMT explicitly.
