    Questions

    How accurate are the clocks?

    They use your device’s clock, so they are as accurate as your computer or phone — usually within a second when it syncs time automatically.

    Are daylight saving changes included?

    Yes. Offsets come from your browser’s time zone database and change automatically when a city switches to or from summer time.
