XFC_ExtendDcTime
The function XFC_ExtendDcTime extends a 32-bit time stamp to 64 bit.
A prerequisite for the extension to a complete time stamp is that the 32-bit time stamp is valid for the current time range. It is not possible to guarantee error-free extension of a time stamp that applies more than approx. +/- 2 seconds before or after the current time.
