That is not the issue I was trying to explain to you.  The Integer you read
from the Registry is *not* stored in the same way as the value that is
stored in a TDateTime.

The Integral portion of a TDateTime is the number of days that have passed
since December 30, 1899, and the fractional portion is the time of the day.

The value that is stored in the Registry, on the other hand, is the number
of seconds that have passed since January 1, 1970, 12:00 AM.

They are *not* the same thing!  So if you want to use the Registry value as
a TDateTime, you must convert one format to the other.  That is what
FileTimeToDateTime() is doing for you in this situation.
