Epoch → date
Enter a Unix epoch (for example 1700000000) and Stamply shows the matching calendar date in your local timezone and in UTC. Copy buttons make it easy to paste results into logs, tickets, or docs.
Seconds vs milliseconds
Classic Unix time uses seconds. JavaScript's Date.now() and many databases use milliseconds. Stamply auto-detects the unit when the magnitude makes it obvious, and you can override with the Seconds / Milliseconds toggle.
