Unix Timestamp
Live epoch seconds and a now button.
Loading tool
Read seconds and milliseconds since 1970-01-01 UTC as they tick. Paste a value to see the matching date.
How to use this tool
- Set the dates or duration. Pick the clocks, dates, or timer length you need.
- Start or calculate. Run the timer or read the difference. Time zones use this browser.
- Copy the result. Copy timestamps or calendar values into your notes.
Live vs convert
The live clock is for 'what is now'. For batch conversion of logs, the epoch converter is the quieter page.
Frequently asked
Is this UTC?
The integer is UTC-based. The decoded clock can show any zone.
Why do some APIs use milliseconds?
JavaScript Date uses ms. Unix traditionally uses seconds. Both are shown.
Can I freeze the clock?
Pause stops the live tick so you can copy.
Does it include leap seconds?
No. Unix time smears or skips them.
Is my clock synced here?
It uses the device clock, not an NTP call from this page.
