When a Microsoft Windows 2000-based, Windows XP-based, or Windows Server 2003-based computer runs in Advanced Configuration and Power Interface (ACPI) mode and uses a high-resolution counter, the system clock may run fast.
This issue may occur if the time increment in a program changes and the Hardware Abstraction Layer (HAL) cannot measure the time interval between successive clock interrupts. This causes the system clock to lose a short period of time. When the HAL misses many time-interval measurements in quick succession, the time loss may be significant.
To work around this issue, use one of the following methods:
