UTL
World Clock
Add any number of time zones to see their current local time, updating every second.
How it works
Each clock reads the current moment and formats it in the selected time zone using your browser's built-in time zone database — the same mechanism behind the Time Zone Converter — so daylight saving is reflected automatically for each city.
Frequently asked
Can I add the same city twice?
No — adding a zone that's already in your list is a no-op, since two clocks for the same zone would always show the same time.
Does this list save between visits?
No — the list resets to the three default cities each time you load the page. If you'd like it to persist, that's a reasonable feature to request.
