But it makes more sense to understand why someone chose to implement time.clock() on Windows the way they did -- this seems very broken to me, and I think it should be changed. Some SVN detective work takes this to all the way back to r7713 (1997-04-02). The original implementation checked by Guido and attributed to Mark Hammond. So, we should ask Mark why he did that.

The thread seems to be at http://groups.google.com/group/comp.lang.python/browse_frm/thread/be32478a4b8e77b6/816d6228119a3474 (although I do seem to recall more discussion of the patch which I currently can't find). I'd be very surprised if any applications rely on the fact that each process starts counting at zero, so if someone can come up with a high-res counter which avoids that artifact I'd expect it could be used.

Cheers,

Mark
