Unix timestamp to readable date, and back
A Unix timestamp (or Epoch time) is the number of seconds elapsed since 1 January 1970 at 00:00:00 UTC, a convention originating in the POSIX standard that became the de-facto format for representing instants in software systems. In JavaScript and many modern databases, the timestamp is expressed in milliseconds. This converter accepts both forms, auto-detects the unit, and displays the date in UTC, local time and ISO 8601.
