Hello all,
Terribly sorry  newbie type question. How to i calculate number of days
to some future
date from current date.

i imagine myself doing this
convert future date to universal-time
convert present date to universal-time

then
(setf difference (- future-universal-time present-universal-time))

finally do something like  (extract-#day-from difference) to get number
of days to the future.

thanks

george

No need to be sorry. you are looking for encode-universal-time and
decode-universal-time

Sounds like a good plan to me.
