DT_TO_SYSTEMTIME

DT_TO_SYSTEMTIME 1:

The "DT_TO_SYSTEMTIME" function allows a PLC variable in DATE_AND_TIME format (DT) to be converted to a Windows system time structure. The system time has a resolution of 1 ms, while the resolution of DATE_AND_TIME is 1 s. The "wMilliseconds" variable in the system time structure therefore always returns the value zero.
