Hy,

the '0' or '' isn't send to the Browser normally.
When the value is '0' or 0 it's converted as date to 1.1.1970 by PHP.
When it's NULL or '' it can be converted to a space-character or a 
no-brake-entitie ( &nbsp; ) from the point of displaying the date correctly.

Even if there occure any bugs with '0' or with '' in ie or any other 
browser:
It's another bug and has to be reported as ne entry in bugtracker.
When something special bug already is known in a first version it's nice 
to include, but browser-dependent bugs shouldn't retard fixing of a very 
old and grave bug.

I hope that my points get more positiv feedback and the problem will be 
solved soon. When my help is appreciated feel free to ask me but first 
I'd like to get your opinion.

Best Regards
David
