Fergus,
Perhaps you could try launching your bash command as such:
START "Timing Myprog" /SEPARATE /HIGH time ./myprog.exe
For more information on the START command enter: START /? | more at the
command line. You may also wish to try it with the /REALTIME priority
setting instead of /HIGH. Haven't tried this myself ever, but it seems
like a reasonable approach.
