difftime? i have a ?

I was asked this ?. The tool that tells you what % of execution time is being used by each function in your program is:

my ? is the answer profile or difftime?

i said profile becuase when i looked up difftime, it said it took the difference between 2 integers but someone told me i was still wrong. Can anyone please explain why its difftime besides the definition i seen in the libro.
Thanks!
