I have heard timing reports from which I have inferred that there are 
timing utilities.  I have not used them.

I do something like this, though:

put the long seconds into junk
put the long seconds into startTime
put the long seconds into endTime
put endTime-startTime into timingOffset
...
put the long seconds into startTime
-- do stuff to be timed here
put the long seconds into endTime

put (endTime-startTime)-timingOffset

This can handle some short times, but the OS can increase the times, so 
throw out outliers.

If what you are doing takes a long time, then you don't need at that 
timingOffset stuff.

(The junk thing is superstition and is probably not needed.)
