What is a Unix timestamp?

A Unix timestamp is the number of seconds (or milliseconds) elapsed since January 1, 1970 00:00:00 UTC. It is the universal standard for date/time storage in software.

How do I know if my timestamp is in seconds or milliseconds?

A 10-digit number is seconds (e.g. 1700000000) and a 13-digit number is milliseconds (e.g. 1700000000000). This tool auto-detects it for you.

What is the 2038 problem?

Systems using 32-bit signed integers to store Unix timestamps will overflow on January 19, 2038 at 03:14:07 UTC (timestamp 2147483647). Modern 64-bit systems are not affected.
