Calculate duration based on %DATETIME%

[mevans]

I was also looking for the elapsed time. I see how to do it from the post. As this post was a few years ago, is that still the best way to get the elapsed time, or are there any built-in macros or functions that return it?

It's no big deal if this is still the best way to do it; I'm just checking as Visual Build has had enhancements since this information.
