World Clock
A fixed UTC clock plus up to 5 customizable locations, updating live.
About the World Clock
This widget keeps a fixed UTC (Coordinated Universal Time) clock always visible alongside up to 5 locations you choose yourself — useful for coordinating meetings, deployments, or calls across timezones. UTC never shifts for daylight saving, which makes it a stable reference point: when a location's local clock shows a different offset in summer versus winter, it's that location's daylight saving rule changing, not UTC. Each location card's time and UTC offset are computed live from your browser's IANA timezone database (the same source system clocks use), so results automatically reflect the correct daylight saving behavior for that specific city on that specific date.
To use it: pick a city from the dropdown and click Add — up to 5 at once — and every clock ticks forward live, once a second. Remove any location with its card's Remove button. Your selections are saved to this browser's local storage, so they persist between visits on this device, though they won't follow you to a different browser or computer since nothing is synced to a server.
