Converts a timestamp in seconds or milliseconds — detected automatically — into ISO 8601, UTC, your local time and a relative description. The live current timestamp is shown too, for when that is all you needed.
Runs entirely in your browser
A Unix timestamp is the number of seconds (or, in many systems, milliseconds) that have elapsed since 1 January 1970 UTC — a compact, unambiguous way for computers to represent a moment in time. Logs, databases and APIs are full of them, but they are unreadable to a human. This converter turns a timestamp into the forms you actually want: ISO 8601, UTC, your local time, and a plain relative description like “3 hours ago”.
It detects automatically whether your input is in seconds or milliseconds, which removes a common source of error — a millisecond value read as seconds lands roughly fifty thousand years in the future. It also shows the live current timestamp, which is often all you needed when you are stamping a record or writing a test.
Everything is computed in your browser using its own date handling, so no data is sent anywhere. Use it to make sense of a log entry, to sanity-check a value your code produced, or simply to grab the current epoch time.
