I still paste Unix timestamps into random converters more often than I want to admit.

created_at: 1729000000

exp: 1735689600

The number is fine. The worry is the same every time: does this page upload what I paste?

What I needed

A tiny converter that:

  • accepts epoch seconds or milliseconds
  • shows UTC (ISO) and local time
  • lets me copy the ISO string
  • has a Use now button for the current timestamp
  • does the work in the browser

So I added one to KeptTools.

Try it
