                     26: unused.  The element ut_line is  the name of the special file for
                     27: the user's terminal, and is normally found in the directory /dev.
                     28: ut_time gives the date and time the user logged into COHERENT.

                     30: The  file /usr/adm/wtmp  maintains  a record  of  all logins  and
                     31: logouts, and may be  summarized by the command ac.  The processes
                     32: login and init write  entries into the file wtmp; neither creates

                     36: Entries in wtmp are identical to those in utmp.  A null string in
                     37: the  ut_name  field  indicates  a  logout.  The  following  three
                     38: special terminal names may be  found in wtmp.  When the system is
                     39: booted, init  writes a  ut_line entry of  `~'.  When the  time is
                     40: changed with the command date,  it writes an entry giving the old
                     41: date (`|')  and an entry giving the new  date (`}').  This allows
                     42: ac to adjust connect times appropriately.
