NAME
  xclock - analog / digital clock for X

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

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 or -d
      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.

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

  -highlight color (or -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 30 seconds or less 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.

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.

X DEFAULTS
  This program uses the 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
      lwhite, 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 lwhite, 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 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
  <XRoot>/lib/X11/app-defaults/XClock
      specifies required resources

BUGS
  xclock believes the system clock.

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