looking at the source of GnomeDateEdit in libgnomeui, it appears that 
the widget is set up so that it always contains some valid date and 
time.  so, er, you may not be able to.

you could set the unix timestamp to 0 and create a wrapper that returns 
undef if the timestamp is 0. ... mmm, that doesn't seem to work, 
though:  after setting the value "0" in the date entry, i get this:

gish: print Dumper( $dateedit->get ('time') )
GLib-CRITICAL **: file gdate.c: line 1273 (g_date_to_struct_tm): 
assertion `g_date_valid (d)' failed at (eval 23) line 1, <FIN> line 18.
$VAR1 = 4294967295;

hrm.
