[ntp:questions] Timekeeping broken on Windows XP with multimedia timer enabled (-M option)

Here's what I see from clockres without the -M option on

Max 15.625 ms
Minimum 1.000 ms
Current 15.625 ms

However when I turn -M on the bottom line changes to Current 0.977 ms

Is that really correct as even I can tell 0.977 is less than the 
"minimun" 1.000 ms" in the previous line?
