27848 2009-07-30 12:04:33 -0700 [WINCE] allow using old GetTickCount implementation of currentTime 2009-07-31 22:26:23 -0700 1 1 1 Unclassified WebKit Web Template Framework 528+ (Nightly build) All Other RESOLVED FIXED P2 Normal --- 23154 0 joenotcharles abarth abarth manyoso yong.li.webkit oldest_to_newest 135914 0 joenotcharles 2009-07-30 12:04:33 -0700 The QueryPerformanceCounter implementation of currentTime has a few problems: despite the workarounds, the clock still occasionally goes backwards (I suspect the 2 sec threshold is too small), and using timeBeginPeriod/timeEndPeriod can affect system performance by changing the frequency of the scheduler. This patch lets you choose the older implementation, despite the lower resolution, by setting WTF_USE_QUERY_PERFORMANCE_COUNTER to 0. 135924 1 33802 joenotcharles 2009-07-30 12:10:06 -0700 Created attachment 33802 patch to CurrentTime.cpp 135930 2 33802 staikos 2009-07-30 12:22:13 -0700 Comment on attachment 33802 patch to CurrentTime.cpp Looks good to me.
