A problem is that after someone's logged out, they're not in utmp any
more, so the real logout time is impossible to get.  The login time
should be OK, however ---- assuming the user is still logged on ---
otherwise it's a bug.

That's hard:  you'd actually have to get the shell itself to wake up
and check every now and then.  You might be best doing it some other
way, like a script running in the background.

That won't do:  it definitely has to be &cb.  The problems will start
when you try completing user names.  It sounds like your problem is
with including the right version of ypclnt.h.  Maybe I didn't put all
the instructions in the FAQ.  At worst, change the #include for
ypclnt.h to 
#include "my_ypclnt.h"
where my_ypclnt.h is the local modified copy of the header with the
corrected prototype.
