Content
Two articles (Microsoft and IBM) about high resolution time on Windows: http://msdn.microsoft.com/en-us/magazine/cc163996.aspx http://www.ibm.com/developerworks/library/i-seconds/ I installed the Windows port of the NTP daemon: http://www.meinberg.de/english/sw/ntp.htm Using the NTP daemon, the resolution is 1 ms instead of 15 ms (on Windows Seven). It looks like it is possible to have a resolution of 0.5 ms, but I failed to get this resolution. Attached patch is much more simple than the previous one: it only changes _PyTime_gettimeofday().
