About TimeThen
Last updated
TimeThen answers one practical question: what time is it there, and what will it be then?
Knowing the time somewhere else is rarely the whole job. You need to know whether it is still office hours in London when you call from Chicago, whether Sydney has changed its clocks yet, or what 3 pm in Kuala Lumpur means for a colleague in New York. TimeThen works those answers out and shows them plainly.
What makes it reliable
- IANA time zones, never fixed offsets. Every city is linked to an IANA time
zone such as
Europe/London, which holds the full history of daylight saving rules and government changes. - Calculated, not copied. Clocks run on your device from those rules, and our pages are rebuilt every day so offsets, differences and upcoming clock changes stay current.
- Tested edge cases. Our time engine is tested against daylight saving gaps and overlaps, the International Date Line, and 30- and 45-minute offsets before every release.
