// OEMInitClock: OPTIONAL

// OEMPowerOff.  The kernel calls OEMPowerOff first, then this function (if
// it is implemented).

// OEMQueryPerformanceCounter: OPTIONAL
//

// milliseconds since the device booted, excluding any time that the system
// was suspended. GetTickCount starts at zero on boot and then counts up from
// there.
//
// For debug configurations, 180 seconds is subtracted from the
// number of milliseconds since the device booted. This enables code that
// uses GetTickCount to be easily tested for correct overflow handling.

// is used in variable-tick timer implementations.
//
// It must set the timer hardware to interrupt at dwTick time, or as soon as
// possible if dwTick has already passed.  It must save any information
// necessary to calculate the g_pNKGlobal->dwCurMSec variable correctly.
