What Epoch Converter is

Unix time in seconds and milliseconds, plus a paste box for an epoch or a datetime. Local and UTC in this browser.

How to use it

  1. Read the live clock, or paste an epoch or a datetime.
  2. Check local and UTC side by side.
  3. Copy the line you need.

Common uses

Debug a log timestamp, check a JWT exp, or turn a Unix value into a wall clock. Leap seconds are not modelled. The browser’s zone is the local column.

Privacy

Numbers and text stay in this tab. We do not log them. Refresh the page and the form is blank. We never see what you copy.
