Yes, that's the wimps at Microsoft making "localtime()" and "gmtime()"
return a null pointer for times before the Epoch (midnight, Jan 1, 1970
GMT) rather than just filling in the "struct tm" sanely.  (The rwho
packet claims that it was received in the year in which the original
Ford flathead V-8 came out; UNIX wasn't around back in 1932....)

The current version of Ethereal in CVS has fixes to the calls to
"localtime()" and "gmtime()" (other than the ones in the SMB dissector,
which were fixed a while ago) to report a "bad time" if "localtime()" or
"gmtime()" return a null pointer.
