The documentation for the DateTime::UniversalTime
states:
"A 64-bit signed integer that represents a point in time as the number of 100-nanosecond intervals prior to or after midnight on January 1, 1601 (according to the Gregorian Calendar)."
This is the same as the Win32 FILETIME
struct which you need to convert to a 100-nanosecond long long value and set it in the DateTime::UniversalTime
field.
