My Windows time is not correct.
Depending on the Windows configuration, the system time may be inaccurate. In this case, the Windows timer should be changed.
In Windows XP/2003
Add / usepmtimer to the boot parameters in boot.ini. For example,
multi (0) disk (0) rdisk (0) partition (1) \ WINDOWS = "Microsoft Windows XP Professional" / noexecute = optin / fastdetect / usepmtimer
In Windows 2008/2008 R2/Vista/7
Use the bcdedit command to change the timer (you need a Windows console with administration rights)
bcdedit / set {default} USEPLATFORMCLOCK on
