Oh... I see what's happening there. The 'Date' as used above is 
actually a function which returns an instance of a DateTimeType, and 
not a class, as you might expect. DateTime is another such function. 
The output from 'd', which is obviously module-generated, is returning 
a misleading value.

Jeff... was the output you got from your code REALLY the output you saw?
