Frequently Asked Questions
How does the world clock handle daylight saving time?
The clock automatically applies DST when the city's time zone observes it. For example, New York shifts from EST (UTC-5) to EDT (UTC-4) in summer. The clock uses the browser's time zone database, which is updated regularly.
Can I add custom cities?
The tool supports major world cities. If your city is not listed, select the nearest major city in the same time zone, or use the Time Zone Converter to find the UTC offset for your location.
Does the clock work offline?
Yes. The clock uses your device's system time and time zone data. It works without an internet connection once the page is loaded. However, if your device clock is wrong, the world clock will also be wrong.
How accurate is the world clock?
The clock is as accurate as your device's system clock. Most devices sync with internet time servers and are accurate to within a second. For precise time needs (e.g., trading), use a dedicated NTP-synced clock.
Can I see the time difference between cities?
Yes. By comparing the times shown for each city, you can see the time difference. For example, if New York shows 3 PM and London shows 8 PM, the difference is 5 hours. The Time Zone Converter can calculate this automatically.
