TDateTime is held as a floating point number. The integral part is days from
the start day sometime in the remote past, the fractional part is the
fraction of a day. So x.0 is midnight; x.5 is noon.

To get your answer, (Time1-Time2) * 24 gives the difference in hours and
fractions of an hour. This will also work if the answer is > 24
