How to use
- 1Enter a timestamp, or a date such as 2026-01-01T09:30:00+01:00.
- 2Leave both fields empty to see the current time.
- 3Read the ISO, RFC 2822, local and relative forms and the time-zone table; click a value to copy it.
Values below 100 billion are read as seconds, larger ones as milliseconds, then microseconds and nanoseconds. Tick “milliseconds” to force milliseconds for small values.
UTC. Add Z or an offset such as +02:00 to be explicit. Dates in other formats are parsed by your browser in local time.
Signed 32-bit Unix time ends on 2038-01-19 03:14:07 UTC. Systems that still store time in 32 bits overflow after that; the tool warns when a value is outside that range.
No. Every day has exactly 86,400 seconds in Unix time, so a leap second (23:59:60) is not counted.
