WWV(1)                                                     WWV(1)

     NAME
          wwv - print and set the date from accurate clock

     SYNOPSIS
          wwv [ -b -s -f -u ]

     DESCRIPTION
          Wwv connects to a clock synchronized with radio station WWV.
          With no argument it prints the time obtained.  It accepts
          these arguments:

          -b   Print both the WWV time and the system's current idea
               of the time.

          -s   Set the system's time to agree with WWV.  You must be
               super-user.  The system time cannot be changed by more
               than 20 minutes.

          -f   With -s, force the time to be set by WWV even if the
               local time disagrees by more than 20 minutes.

          -u   Report time in UTC rather than local time.

     FILES
          /usr/adm/wtmp to record time-setting

     BUGS
          The WWV clock has been observed to slip sync by an integral
          number of minutes or hours from the radio standard.
