Days between dates

Days between dates

[Chry Cheng]

How does one calculate the no. of days between two dates in Elisp?  So
far, I have the following:

(decode-time (time-subtract (date-to-time "...") (date-to-time
"...")))

But decode-time returns dates.  I was wondering if there already is a
function somewhere unknown to me that would do this.
