 NAME
      xclock - analog / digital clock for X

 SYNOPSIS
      xclock  [-toolkitoption ...] [-help] [-analog] [-digital] [-chime] [-hd
      color]
              [-hl color] [-update seconds] [-padding number]

 DESCRIPTION
      The xclock program displays the time in analog or digital form.  The
      time is continuously updated at a frequency which may be specified by
      the user.  This program is nothing more than a wrapper around the
      Athena Clock widget.

 OPTIONS
      Xclock accepts all of the standard X Toolkit command line options
      along with the additional options listed below:

      -help   This option indicates that a brief summary of the allowed
              options should be printed on the standard error.

      -analog This option indicates that a conventional 12 hour clock face
              with tick marks and hands should be used.  This is the
              default.

      -digital
              This option indicates that a 24 hour digital clock should be
              used.

      -chime  This option indicates that the clock should chime once on the
              half hour and twice on the hour.

      -hd color
              This option specifies the color of the hands on an analog
              clock.  The default is black.

      -hl color
              This option specifies the color of the edges of the hands on
              an analog clock, and is only useful on color displays.  The
              default is black.

      -update seconds
              This option specifies the frequency in seconds at which xclock
              should update its display.  If the clock is obscured and then
              exposed, it will be updated immediately.  A value of less than
              30 seconds will enable a second hand on an analog clock.  The
              default is 60 seconds.

      -padding number
              This option specifies the width in pixels of the padding
              between the window border and clock text or picture.  The

              default is 10 on a digital clock and 8 on an analog clock.

 X DEFAULTS
      This program uses the Athena Clock widget.  It understands all of the
      core resource names and classes as well as:

      width (class Width)
              Specifies the width of the clock.  The default for analog
              clocks is 164 pixels; the default for digital clocks is
              whatever is needed to hold the clock when displayed in the
              chosen font.

      height (class Height)
              Specifies the height of the clock.  The default for analog
              clocks is 164 pixels; the default for digital clocks is
              whatever is needed to hold the clock when displayed in the
              chosen font.

      update (class Interval)
              Specifies the frequency in seconds at which the time should be
              redisplayed.

      foreground (class Foreground)
              Specifies the color for the tic marks. The default depends on
              whether reverseVideo is specified.  If reverseVideo is
              specified the default is white, otherwise the default is
              black.


      hands (class Foreground)
              Specifies the color of the insides of the clock's hands. The
              default depends on whether reverseVideo is specified.  If
              reverseVideo is specified the default is white, otherwise the
              default is black.

      highlight (class Foreground)
              Specifies the color used to highlight the clock's hands. The
              default depends on whether reverseVideo is specified.  If
              reverseVideo is specified the default is white, otherwise the
              default is black.

      analog (class Boolean)
              Specifies whether or not an analog clock should be used
              instead of a digital one.  The default is True.

      chime (class Boolean)
              Specifies whether or not a bell should be rung on the hour and
              half hour.

      padding (class Margin)
              Specifies the amount of internal padding in pixels to be used.

              The default is 8.

      font (class Font)
              Specifies the font to be used for the digital clock.  Note
              that variable width fonts currently will not always display
              correctly.

 WIDGETS
      In order to specify resources, it is useful to know the hierarchy of
      the widgets which compose xclock.  In the notation below, indentation
      indicates hierarchical structure.  The widget class name is given
      first, followed by the widget instance name.
