About timestamp conversion
Numeric Unix timestamps only
This converter accepts numeric Unix timestamps and infers seconds, milliseconds, microseconds, or nanoseconds from the input magnitude. After conversion you can still switch the assumed unit manually to check ambiguous values.
Local, UTC, and relative views
Results include your local time, UTC, ISO 8601, RFC 2822, and relative differences from the moment you run the conversion. For free-form date strings, timezone assumptions, and richer format lists, 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, the converted result shows both your local timezone and UTC time, making it easy to compare times across different regions.
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.
