Frequently Asked Questions About World Clock
How accurate is the world clock?
The world clock uses your device's system clock combined with timezone offset data. Accuracy depends on your device's time synchronization. Most modern devices sync via NTP and are accurate to within milliseconds.
Does this account for Daylight Saving Time?
Yes. DST transitions are handled automatically based on the IANA timezone database offsets. Clocks update correctly when cities enter or leave DST.
How many cities can I add?
You can add as many cities as you like. Each clock tile updates independently.
