Well, there is the possibility of passing null values through xml-rpc.
I believe there is an optional keyword argument in some of the
xmlrpclib functions to allow it.  Basically it translates None to
<nil/> in the xml.

The DateTime type must be defined somewhere.  Is it an adodb type?  If
so, you could do something like this:

if type(value) == adodb.DateTime:
    ...
