NAME

       xclock - analog / digital clock for X


SYNOPSIS

       xclock  [  -help	 ]  [ -analog ] [ -digital ] [ -brief ] [
       -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.


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.

       -brief  This  option  indicates	that  the  digital  clock
	       should only display the hours and minutes  fields.
	       The  default  is	 to  show  the full time and date
	       information.

       -utime or -d
	       This option indicates that a digital clock  should
	       display	 seconds   since  the  Epoch  (in  format
	       '970012340 seconds since Epoch' instead of a stan
	       dard 24-hour time.

       -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.


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 digi
	       tal 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 reverseV_
	       ideo 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.

       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 struc
       ture.  The widget class name is given first,  followed  by
       the widget instance name.

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_MAN
	       AGER property.


FILES

BUGS

       Xclock believes the system clock.

       When in digital mode, the string should be centered  auto
       matically.
