Convert epoch and calendar dates

The Unix timestamp converter maps epoch seconds and milliseconds to calendar time and back. Local and UTC views help with log analysis and exp fields in tokens.

Epoch to date and time

Drop a timestamp from JSON, a Date header, or a broker message and read a human clock value.

Length hints distinguish 10-digit seconds from 13-digit milliseconds automatically.

Date and time to epoch

Pick a moment and get seconds for APIs or databases. Duration hints estimate gaps between two marks.

When scheduling cron or TTL, double-check UTC versus local—off-by-one-hour bugs are usually timezone issues.
