Unix timestamp converter

How it works

A Unix timestamp counts the time since 1 January 1970 00:00:00 UTC. Paste a number and the unit is detected from its length: up to 11 digits is seconds, 12–13 milliseconds, 14–16 microseconds and 17–19 nanoseconds. A millisecond value from before March 1973 has 11 digits or fewer and is read as seconds.

Leap seconds are not counted in Unix time, so every day has exactly 86,400 seconds. Results use the same time zone database as the rest of clocknow.
