FAQ

What is a Unix timestamp?

The number of seconds elapsed since 1 January 1970 00:00:00 UTC, ignoring leap seconds. Milliseconds variants are the same value times 1000.

Why does my timestamp show a date in 1970?

You likely pasted a millisecond value into a seconds field or vice versa. 13-digit values are milliseconds, 10-digit values are seconds.
