Logs and APIs are full of bare integers that are meaningless until converted, and the first question is always whether it is seconds or milliseconds. Guessing wrong puts you in 1970 or fifty thousand years out.
Paste a timestamp and it is detected and shown as ISO 8601, UTC and your local time at once, with the relative distance from now. It converts the other way too, and the current epoch is always displayed for reference.
What people open it for

- Working out a JWT's expiry as a real date
- Generating an epoch value for a fixture or a query
