amount of time a program spends in a
particular part of the program.

Please post linux-specific questions to one of 'comp.os.linux.*'
newsgroups. Here we talk C++ language only.

What you need is a profiler.
Try google for one.

its an OT question, but since you are an FC user try:

look for "Cachegrind" tool and "Callgrind" front end.
