About timestamp conversion
Verify the timestamp unit before trusting the date
Paste a Unix timestamp and the workbench detects seconds, milliseconds, microseconds, or nanoseconds. You can override the unit, inspect the exact equivalent values, and see when browser date projection is limited to milliseconds.
One point in time, several local clocks
Every timezone row points to the same UTC instant; only the displayed clock changes. You can also reverse the process from a structured local date and IANA timezone. For free-form date strings, use the flexible time format converter instead.
FAQ
Common questions and answers about this topic.
What timestamp formats are supported?
This tool supports Unix timestamps in seconds, milliseconds, microseconds, and nanoseconds. It automatically detects the unit based on the magnitude of the input.
What is a Unix timestamp?
A Unix timestamp is the number of seconds (or milliseconds) elapsed since January 1, 1970 00:00:00 UTC (the Unix epoch). It is widely used in programming, databases, and APIs to represent points in time.
Can I convert between timezones?
Yes. Compare UTC, your system timezone, and another IANA timezone in the same result. In reverse mode, the selected source timezone determines which instant the entered clock time represents.
Is my data sent to any server?
No, timestamp conversion runs entirely in your browser. Your timestamps are parsed and converted locally with JavaScript — nothing leaves your device.
