FAQ
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 widely used in computer systems as a time representation.
What is the difference between seconds and milliseconds?
Second-level timestamps are 10 digits; millisecond-level are 13 digits. JavaScript and most modern systems use milliseconds, while traditional Unix/Python uses seconds. This tool automatically handles both.
Are timestamps affected by timezone?
Unix timestamps are UTC-based and timezone-independent. When converting to a datetime, the tool displays in your browser's local timezone.
