Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (also called Epoch time) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC. It's the standard way computers represent time internally and is widely used in programming, databases, and APIs.
What is the difference between seconds and milliseconds timestamps?
Unix timestamps in seconds are 10 digits (e.g., 1711382400). Millisecond timestamps are 13 digits (e.g., 1711382400000). JavaScript's Date.now() returns milliseconds. This tool auto-detects which format you're using.
