KeQueryTimeIncrement function (wdm.h)
The KeQueryTimeIncrement routine returns the number of 100-nanosecond units that are added to the system time each time the interval clock interrupts.
This function has no parameters.
KeQueryTimeIncrement returns a ULONG value indicating the number of 100-nanosecond units that are added to the system time each time the interval clock interrupts.
At startup time, the operating system determines the time increment to use for the system time. This time increment remains constant until the computer restarts. During this time, calls to KeQueryTimeIncrement always return the same time increment value. The time increment does not change while the computer is running, and it does not change as the result of a suspend-resume cycle.
