How to record excution time of a subfunction during runtime?

I have a function, that repeatedly calls a specific subfunction and I need to record the execution time of every call. How can I do that with profile? The help page for profile didn't go into how the time is recorded, if it is.

Can I just time the call from the outside or do I have to change the subfunction to record it's own runtime and return with all the other values?

Daniel, use tic and toc.

 tic
 [your subroutine call or commands]
 toc
