Just to re-iterate what Dave said, don't use this technique for timing 
small code snippets, it isn't accurate enough to give meaningful 
results. For that, use timeit. 

But for reporting how long some big chunk of work took, that's perfectly 
fine, e.g. if you expect to print something like this:

"Processed 1734 records in 8.2 seconds."
