About timestamp converter
A Unix timestamp counts the seconds since 1 January 1970 UTC. It is compact and unambiguous, which is why logs and APIs use it — and unreadable at a glance, which is why this exists.
The most common source of confusion is the unit. Some systems emit seconds, others milliseconds, and a millisecond value read as seconds lands roughly fifty thousand years in the future. This tool infers the unit from the magnitude and shows you which it assumed.
Good to know
- Both directions work: paste a timestamp to get dates, or pick a date to get the timestamp in seconds and milliseconds.
- Every result is shown in your local timezone and in UTC, because mixing the two is the second most common source of timestamp bugs.
- The relative age ("3 hours ago") is usually the fastest way to sanity-check that you are looking at the record you expected.
