In Lyric, with the CL compiler, (DATE) seems to be treated as
a constant.  For example,

(DEFINEQ (a () (DATE)))

Calling a when it's interpreted correctly returns the current date, 
which is different each time.  

Now:

(CL:COMPILE 'a)

Now calling a gives the same answer each time, the time at which a
was compiled.
