SAP Note 1036194 - OS timers are not synchronized

Summary :
SAP systems on Windows Server 2003 or 2008 may experience issues with high-resolution timers due to unsynchronized processor registers which affect the WIN32 API's QueryPerformanceCounter, resulting in erroneous timestamps. This discrepancy arises because processor frequencies are adjusted based on load, which is not uniformly handled across processors, leading to synchronization failures. Solutions include updating CPU drivers before system installation on Windows Server 2003 and using the `bcdedit /set {current} useplatformclock true` command for Windows Server 2008, followed by a system reboot to ensure appropriate timer settings.
