std.perf.HighPerformanceCounter uses the same Windows API but will convert 
to seconds, milliseconds, and microseconds for you.  It's cross-platform, 
too, using gettimeofday on *nix platforms.

Unfortunately if David is looking to use this as a timestamp, i.e. in files, 
the value you get from QPC doesn't represent any useful amount of time IIRC. 
It's just a counter incremented by the processor from the time the computer 
starts.
