Pro Tips

  • Negative timestamps represent dates before January 1, 1970. For example, -86400 is December 31, 1969.
  • JavaScript uses milliseconds: Date.now() returns a 13-digit timestamp.
  • In Python, use int(time.time()) for seconds or int(time.time() * 1000) for milliseconds.
  • The Year 2038 problem affects 32-bit systems which cannot represent timestamps after 2,147,483,647 (Jan 19, 2038).
  • Timestamps are always UTC. When you see different “times” for the same timestamp, it is the same instant displayed in different timezones.

What Is an Epoch Converter?

An epoch converter translates Unix timestamps (seconds since January 1, 1970 UTC) into human-readable dates and times. Developers, DevOps engineers, and data analysts use epoch converters daily when working with logs, APIs, databases, and system events that store time as numeric timestamps.

Frequently Asked Questions

What is an epoch timestamp?

An epoch (or Unix) timestamp is the number of seconds since January 1, 1970 00:00:00 UTC. It's a standard way to represent time in computing.

What's the difference between seconds and milliseconds timestamps?

Unix timestamps in seconds are 10 digits (e.g., 1678886400). Millisecond timestamps are 13 digits (e.g., 1678886400000). JavaScript uses milliseconds, while most Unix systems use seconds.

Does this handle time zones?

Yes. Convert timestamps to any time zone and see the UTC offset. The tool auto-detects your local time zone.

Can I batch convert multiple timestamps?

Yes. Paste multiple timestamps (one per line) and convert them all at once.

What is the Year 2038 problem?

32-bit systems store Unix timestamps as signed 32-bit integers, which overflow on January 19, 2038. 64-bit systems are not affected.
