NAME
       dclock - digital clock

SYNOPSIS
       dclock [ -cmjd ] [ -sslant ] [ -tthickness ] [ -frate ]

DESCRIPTION
       Dclock displays a scalable digital clock.  The time is updated from the local host clock every minute as a background process.  The current
       date is displayed across the top of the window in the format

       Sat Aug 16 1986

       (or some subset of such if there's not enough room).  Options to control the clock's appearance, size and placement are as follows:

       -c              Display in 12-hour format ("civilian" time) -- the default.

       -m              Display in 24-hour format ("military" time).

       -j              "John's flag."  Puts a tail on the digit `9'.

       -d              Do not display the current date across the top of the clock view.

       -b              Display a border (horizontal line) between the date string and the time display.

       -T              Do not display the Time in the clock view (leaving just the date).

       -sslant         Set the slant of the digits.  A slant of 100 (the maximum) corresponds to a slant of one digit width.  A slant  of  0  (the
                       minimum) is vertical.  Default is -s30.  A special form is -s, which is equivalent to -s0.

       -tthickness     Set  the  thickness  of  the digit segments.  Allowable values are between 5 and 25.  A thickness of 25 results in segments
                       which are one quarter (25%) of the digit width. Default is -t15.

       -frate          Set the rate at which the segments fade when the time changes.  A value of 0 is fastest and 4 is slowest.  Default is  -f4.
                       A special form is -f, which is equivalent to -f0.

       To exit dclock, type a `q' in the window.
