It would take over 4 billion operations in a single timer tick (on the order 
of nanoseconds) to make tm_usub overflow. That seems pretty unlikely.

I suppose that's always possible...

The original post shows that the tm_usec field is negative. That could happen 
if the offset we computed between the SYSTEMTIME and the PerformanceCounter 
was wrong, or if the SYSTEMTIME was adjusted while the process was running.

What version of Windows are you running? 32 or 64 bit? Can you singlestep 
through this function with a debugger and verify all of the values? I haven't 
run this code on Windows in a long time, would take a bit of effort to 
resurrect my build environment.
