Frequently asked questions
What is a Unix timestamp?
A Unix timestamp (epoch time) counts the number of seconds (or milliseconds) that have elapsed since January 1, 1970, 00:00:00 UTC. It's a common way to represent a point in time in a timezone-independent, easily-comparable format.
How do I tell seconds from milliseconds?
As of 2026, second-based Unix timestamps are 10 digits long, while millisecond-based ones are 13 digits long. This tool auto-detects which one you pasted based on digit count.
