In my endeavor to write a conversion utility for ISO 8601 dates, I came
across a puzzle which I wonder if anyone can solve.

How does a Date variant know when to display the time portion only when
converting to a BSTR?

As you are probably aware, Date variants are actually double values,
where each day is a value of 1, and an hour is 1/24. The documentation
appears hazy to me; it suggests to me that if the integer portion is
dropped, then only the time should be displayed. However, I have
discovered that:

0.52494212962963 displays as: "12:35:55 PM"

but

0.52494212963211 displays as: "12/30/1899 12:35:55 PM"

What gives?
