     Name
          clock - the system real-time (time of day) clock


     Description
          The clock  file  provides  access  to  the  battery-powered,
          real-time  time  of day clock. Reading this file returns the
          current time; writing to the file  sets  the  current  time.
          The time, 10 bytes long, has the following form:
               MMddhhmmyy
          where MM is the month, dd is the day, hh is the hour, mm  is
          the  minute,  and yy is the last two digits of the year. For
          example, the time:
          0826150389 is 15:03 on August 26, 1989.
