XCLOCK(1X11)            COMMAND REFERENCE            XCLOCK(1X11)



NAME
     xclock - analog / digital clock for X

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

     This is a user-contributed client.

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
     This program accepts all standard X Toolkit command line
     options along with the additional options listed here:

     -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 preferred 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 the commands listed here.

     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.

CAVEATS
     The xclock program 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.
