World Clock: Live Times & UTC Offsets
The world clock displays the current local time in Istanbul, London, New York and Tokyo, alongside each city’s current UTC offset. The cards refresh once per second using the browser’s international date and time formatting support.
This page compares clocks for the present moment. It does not convert a user-entered date and time; use the linked time zone converter when you need to plan an event for a specific date.
When is it useful?
- Checking whether colleagues or friends in another listed city are likely to be awake.
- Comparing current UTC offsets before scheduling an online meeting.
How to use it
- Open the world clock page; no account or time input is required.
- Compare the four live local-time cards and read the UTC offset shown beneath each city.
- For a future or past date, open the time zone converter because daylight-saving rules can change an offset.
Example
Input: Open the live clock with no date or time entered.
Output: Istanbul, London, New York and Tokyo cards showing current local time and the current UTC offset for each city.
Who is it for?
- Remote teams coordinating across the four listed cities
- People checking current local time before making an international call
- Event organizers comparing current UTC offsets
Privacy and limitations
The clock formats the current time locally in your browser with the built-in Intl date and time APIs. It does not send a clock query to a server, request location, or read a calendar.
