What Time Is It?
The exact time right now with your time zone, UTC offset, Unix timestamp and ISO 8601 string, plus a live world clock for eighteen major cities.
How to use it
- The clock reads from your device, so it is exactly as accurate as your system time.
- Switch between 12 and 24 hour display with the toggle.
- The world clock shows the current time and weekday in each zone.
This shows the current time read straight from your device's own clock, alongside the details a plain clock does not give you: your detected time zone name, the UTC offset, a Unix timestamp and an ISO 8601 string — the handful of formats that come up constantly in scheduling, logging and software work.
Unix timestamp and ISO 8601
A Unix timestamp is the number of seconds elapsed since 1 January 1970 UTC, and it carries no time zone information of its own — that is precisely why software stores time internally as a timestamp and converts to a readable, zone-specific format only when displaying it. An ISO 8601 string, like 2026-08-23T14:30:00Z, is the readable equivalent, sortable as plain text and unambiguous across systems, which is why it is the standard format for APIs and log files.
The world clock
Eighteen major cities are shown alongside your own time, each with its current local time and weekday, updating live. It is a fast way to check whether it is a reasonable hour to call someone on another continent, or to sanity-check a meeting time before sending an invite across time zones.
Questions people ask
Where does this time come from?
Your own device's clock. If it looks wrong, your system time or time zone is wrong — most operating systems can sync it automatically over the network.
What is a Unix timestamp?
The number of seconds since 1 January 1970 UTC. It is time zone free, which is why it is what most software stores internally.
Is anything uploaded or stored on a server?
No. Everything runs in your browser. Anything that persists is kept in this browser's local storage on your own device.
