Time Conversions

The following functions can convert 64-bit high resolution times to seconds, milliseconds, microseconds, nanoseconds, and vice versa:

RTKFTIMEINT FTTimeToSeconds  (const RTKFineTime * T);
RTKFTIMEINT FTTimeToMilliSecs(const RTKFineTime * T);
RTKFTIMEINT FTTimeToMicroSecs(const RTKFineTime * T);
RTKFTIMEINT FTTimeToNanoSecs (const RTKFineTime * T);

void FTSecondsToTime  (RTKFineTime * T, DWORD Secs);
void FTMilliSecsToTime(RTKFineTime * T, DWORD Millis);
void FTMicroSecsToTime(RTKFineTime * T, DWORD Micros);
void FTNanoSecsToTime (RTKFineTime * T, DWORD Nanos);

All return values are rounded down. Again, the return values of the first four functions limit the available range. RTKFTIMEINT can be a 32-bit or 64-bit integer type. Please see section Module FineTime in the RTKernel-32 Programming Manual for details.
