Frequently Asked Questions

What is a Unix timestamp?
A Unix timestamp is the number of seconds (or milliseconds) that have elapsed since January 1, 1970 at 00:00:00 UTC (the "Unix epoch"). It is a standard way to represent a moment in time in programming.
How do I know if my timestamp is in seconds or milliseconds?
Timestamps in seconds are typically 10 digits (e.g., 1711900000), while timestamps in milliseconds are 13 digits (e.g., 1711900000000).
Does the tool support negative timestamps?
Yes. Negative Unix timestamps represent dates before January 1, 1970.
What time zones are shown?
The tool shows UTC and your browser's local time zone automatically.
