[QUOTE="davidf, post: 661473, member: 19484"] I can't see what's wrong yet (how is m_dAdjustment calculated?) but the figures are not what I expected. The stats on my machine show a constant 1.0003 which would add up to a clock drift of just over 1 second per hour or 24 seconds per day. It could be in the Audio Clock I suppose but I'm certainly not seeing my clock go off by 3.5 minutes per week. From your previous samples I calculated the multiplier over the 100 seconds and got [code] 1.025641026 1.033352838 0.988735232 1.001775899 0.995644405 1.001562247 1.000780999 1.001797268 1.000702905 1.001494482 1.000596414 0.998207012 0.999618143 1.000012975 1.000043739 0.974490926 0.999941171 1.000030931 1.000012306 1.000063017 1.000029069 1.000061145 0.999831872 0.999821214 0.999520431 0.999628714 1.00001548 1.000051558 1.000002572 0.999973146 1.000040886 1.000033127 0.999562469 1.000042323 1.000054706 1.000017365 0.999964128 1.000018537 0.999796572 1.000038036 1.000047515 1.000048656 1.00004625 1.000046214 1.000003538 1.000042427 1.000025842 1.000045783 0.999837386 1.00004325 1.000025625 0.999894569 0.999987454 1.000037607 1.000030734 0.999826985 1.000033887 1.000033856 0.999831319 0.999735537 0.999789313 1.000015096 [/code] as the system clock multiplier which is less than you got. Also there is a fair amount of variation over this time which I didn't see in the stats when I tried it last night, the figure was a constant 1.0003. I'll have a look tonight after I give up on trying to fix my RAID disk which failed while I was on holiday - wish I hadn't used RAID 0 now :-( [/QUOTE]
