Frequently asked questions
Where does the timezone list come from?▾
We use IANA timezone identifiers (like "America/New_York") through your browser's Intl APIs, so daylight saving rules are always current.
How accurate are the clocks?▾
Clocks tick once per second from your device's local time. Accuracy depends on your system clock — sync via NTP for best results.
Can I add a city not in the list?▾
We seed the most common IANA zones. If your city isn't shown, pick the nearest one in the same zone — they share the same time.
