FILETIME_TO_DT

The function "FILETIME_TO_DT" converts the time in FILETIME format to DATE_AND_TIME format (DT). The DT format has a smaller value range than the FILETIME format and only offers second accuracy. For this reason the FILETIME value to be converted is limited. The permitted minimum corresponds to value DT#1970-01-01-00:00:00 and the maximum to value DT#2106-02-06-06:28:15. Milliseconds are not considered in the conversion and are rounded down to the DATE_AND_TIME return value accordingly.
