     DATE(1)                                                   DATE(1)

     NAME
          date, clock - date and time

     SYNOPSIS
          date [ option ] [ seconds ]
          clock

     DESCRIPTION
          Print the date, in the format

               Tue Aug 16 17:03:52 CDT 1977

          The options are

          -u   Report Greenwich Mean Time (GMT) rather than local
               time.

          -n   Report the date as the number of seconds since the
               epoch, 00:00:00 GMT, January 1, 1970.

          -i   Report the date as ISO-8601 without time and timezone
               suffix.

          -t   Report the date as ISO-8601 with time and timezone suf-
               fix.

          -m   Report the date as an email compatible (RFC2822) time
               stamp.

          The conversion from Greenwich Mean Time to local time
          depends on the $timezone environment variable; see ctime(2).

          If the optional argument seconds is present, it is used as
          the time to convert rather than the real time.

          Clock draws a simple analog clock in its window.
