NAME
     xclock - analog / digital clock for X

SYNOPSIS
     xclock [-toolkitoption ...] [-option ...]

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.

     The following standard X Toolkit command line arguments are commonly used
     with xclock:

     -bg color
             This option specifies the color to use for the background of the
             window. The default is white.

     -bd color
             This option specifies the color to use for the border of the
             window.  The default is black.

     -bw number
             This option specifies the width in pixels of the border
             surrounding the window.

     -fg color
             This option specifies the color to use for displaying text.  The
             default is black.

     -fn font
             This option specifies the font to be used for displaying normal
             text.  The default is 6x10.

     -rv     This option indicates that reverse video should be simulated by
             swapping the foreground and background colors.

     -geometry geometry
             This option specifies the prefered size and position of the clock
             window.

     -display host:display
             This option specifies the X server to contact.

     -xrm resourcestring
             This option specifies a resource string to be used.

X DEFAULTS
     This program uses the Clock widget in the X Toolkit.  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 black since
             the core default for background is white.

     hands (class Foreground)
             Specifies the color of the insides of the clock's hands.

     highlight (class Foreground)
             Specifies the color used to highlight the clock's hands.

     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.

     reverseVideo (class ReverseVideo)
             Specifies that the foreground and background colors should be
             reversed.

BUGS
     Xclock believes the system clock.

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

     When specifying a time offset, the grammar requires an hours field but if
     only minutes are given they will be quietly ignored.  A negative offset
     of less than 1 hour is treated as a positive offset.

     Digital clock windows default to the analog clock size.

     Border color has to be explicitly specified when reverse video is used.
