Frequently Asked Questions
How does this stay accurate through daylight saving changes?
It uses your browser's built-in time zone database (the same one operating systems use), which already knows every region's daylight saving rules and switch dates — so the displayed time and UTC offset automatically adjust on the correct dates without this tool needing any manual updates.
Can I customize which cities are shown?
Yes — remove any city with its "✕" button, and add others by typing into the search box above the clocks. Your customized list is saved in your browser's local storage, so it's still there the next time you visit.
Is this the same as the Time Zone Converter tool?
No — the Time Zone Converter is for converting one specific time from one zone to another (like scheduling a meeting). This World Clock instead shows the current, continuously updating time in several places at once.
Is any of this sent to a server?
No — all the time calculations happen entirely in your browser, and your customized city list is only saved locally on your own device.
