LOL --- it did, sort of.

The problem is that you didn't know the special meaning of 12/31/1969    
Now if the program had returned 00/00/0000 you would have understood 
that you had a bad date. In other words, ZERO

By a convention adopted long ago, computers measure time in microseconds 
since "time zero" which was chosen to be midnight, 12/31/69 (before Y2K 
we tended to write years two digit if we meant in the 1900's). That 
makes the "zero date" a VALID date (00/00/0000 would not be valid in a 
field expecting a date)
