NAME

       xclock - analog / digital clock for X

SYNOPSIS

       xclock [ -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.

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.

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 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 reverseV-
	       ideo 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

       <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.
