[plt-scheme] (time-apply) questions

 From the manual:
(time-apply proc arg-list) invokes the procedure proc with the arguments 
in arg-list. Four values are returned: a list containing the result(s) 
of applying proc, the number of milliseconds of CPU time required to 
obtain this result, the number of ``real'' milliseconds required for the 
result, and the number of milliseconds of CPU time (included in the 
second result) spent on garbage collection.

Does CPU time or real time include the garbage collection time?
