About Unix timestamps
A Unix timestamp counts time from January 1, 1970 at 00:00:00 UTC. Many APIs, databases, logs, and scheduling systems use timestamps because they are compact and timezone-neutral.
This converter accepts timestamps in seconds or milliseconds and shows ISO, UTC, and local time representations.
Common uses
- Read timestamps from logs
- Debug API response times
- Compare UTC and local dates
- Check whether a value is seconds or milliseconds
Notes
Ten-digit values are usually seconds. Thirteen-digit values are usually milliseconds. Local time depends on your browser timezone.
