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.
