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 is depends on
              whether reverseVideo is specified.  If reverseVideo is specified
              the default is lwhite, otherwise the default is black.


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

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

      XClock  xclock
           Clock  clock


ENVIRONMENT
      DISPLAY to get the default host and display number.

      XENVIRONMENT
              to get the name of a resource file that overrides the global
              resources stored in the RESOURCE_MANAGER property.

FILES
      /usr/lib/X11/app-defaults/XClock - specifies required resources

BUGS
      Xclock believes the system clock.

      When in digital mode, the string should be centered automatically.
