What is a Unix timestamp?

A Unix timestamp is the number of seconds elapsed since January 1, 1970 00:00:00 UTC (the 'Unix epoch'). It's a simple, timezone-independent way to represent a specific moment in time.

Why do some timestamps have 13 digits?

13-digit timestamps are milliseconds since epoch (used by JavaScript's Date.now()). 10-digit timestamps are seconds (used by Unix/Linux). This tool handles both.

What will happen in 2038?

32-bit Unix timestamps overflow on January 19, 2038. Modern systems use 64-bit timestamps which won't overflow for billions of years.

What timezone does this use?

Conversions show both UTC and your local timezone so you can see both representations.
