Sets VARIABLE to a string representing the current time. It is formatted according to FORMAT if specified, otherwise it is formatted as the number of seconds (excluding leap seconds) since the UNIX epoch (01 Jan 1970 00:00:00 UTC).

If the SOURCE_DATE_EPOCH environment variable is set, it uses the value of that variable instead of the current time. See If SOURCE_DATE_EPOCH is set but cannot be properly interpreted as a UNIX timestamp, then execute ACTION-IF-FAIL if specified, otherwise error.
