ANSI Common Lisp 25 Environment 25.2 Dictionary of Environment

25.2.2 encode-universal-time	function

Syntax:

encode-universal-time second minute hour date month year &optional time-zone
universal-time

Arguments and Values:

second, minute, hour, date, month, year, time-zone - the corresponding parts of a decoded time. (Note that some of the nine values in a full decoded time are redundant, and so are not used as inputs to this function.)

universal-time - a universal time.

Description:

encode-universal-time converts a time from Decoded Time format to a universal time.

If time-zone is supplied, no adjustment for daylight savings time is performed.

Examples:

(encode-universal-time 0 0 0 1 1 1900 0) 0 (encode-universal-time 0 0 1 4 7 1976 5) 2414296800 ;; The next example assumes Eastern Daylight Time. (encode-universal-time 0 0 1 4 7 1976) 2414293200

Clarification:

In the last example, the assumption is the machine running Common Lisp is using (United States) Eastern Daylight Time, not that Common Lisp assumes that.

None.
