Questions
How accurate is this clock?
It shows your device's clock, which is usually synchronised with internet time servers within a fraction of a second.
Why does a city show +1?
It is already the next day there. −1 means it is still the previous day.
Does the world clock handle daylight saving time?
Yes. Times are calculated with your browser's time zone database, which includes summer time rules.
Can I remove a city?
Yes, every city in the list has a Remove button. Your list is saved on this device.
