Frequently Asked Questions

What is a Unix timestamp?

A Unix timestamp (or epoch time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It's a standard way to represent time in computing.

What is the difference between seconds and milliseconds?

Unix timestamps are traditionally in seconds (10 digits), but many programming languages use milliseconds (13 digits). This tool auto-detects which format you're using.

What is the Year 2038 problem?

Systems using 32-bit integers to store Unix timestamps will overflow on January 19, 2038. Most modern systems use 64-bit integers to avoid this.
