What is the correct way to store dates in Common Lisp? The closest thing I found for an answer is this , which doesn't actually cut it for me.
How about ENCODE-UNIVERSAL-TIME?
ENCODE-UNIVERSAL-TIME
(defparameter *my-birth-date* (encode-universal-time 0 0 0 14 2 1984))
If you want to keep the date converted to a string, you can use the following:
(multiple-value-bind (s m h d mm y dw dst-p tz) (get-decoded-time) (format nil "~D\/~D\/~D" date month year))
