Why systems use Unix timestamps

Storing a date as a single number (seconds since a fixed reference point) avoids the timezone and format ambiguities that come up when comparing dates as text. That's why APIs, databases and logs commonly record dates this way.

About time zones

The timestamp-to-date conversion uses UTC. If you need local time, you'll need to adjust manually for your timezone offset.

When should you use this tool?

  • Developers

    Figure out what date a timestamp found in a log or database corresponds to.

  • APIs

    Convert a date to the numeric format an endpoint expects.

  • Debugging

    Check whether a timestamped event happened on the expected date.
