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
