About the time in London
London runs on America/Chicago, which puts the city UTC −5 from Coordinated Universal Time right now. The clock at the top of this page is not copied from your device: it is anchored to our reference timestamp and re-rendered every second against the IANA time zone database, so it stays right even when a laptop or phone has quietly drifted.
If you are coordinating from another country, the shortcut is the working window: a normal London day of 09:00–17:00 falls between 14:00–22:00 UTC. Convert your own hours into UTC once and you can tell at a glance whether someone there is likely to be at their desk.
The zone identifier America/Chicago is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/Chicago keeps pointing at Chicago time whatever the date, which is why every timestamp on this page is built from it.
