What is a Unix timestamp?

It is the number of elapsed seconds or milliseconds since 1970-01-01 00:00:00 UTC.

Seconds vs milliseconds

10-digit values are usually seconds and 13-digit values are milliseconds. This tool auto-detects millisecond input.

What is timezone?

The same point in time can look different by region. Check UTC, KST, JST and more at once.

KST/JST/UTC differences

KST and JST are both UTC+9. UTC is the base reference used for system logs.

Common use cases

Useful for validating deploy times, event logs, and expiry timestamps.
