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

       -strftime format
               This option allows an strftime(3) format string to be specified
               for the digital clock's display.

       -twelve This  option  indicates that a digital clock should display the
               time in twelve hour format.

       -twentyfour
               This option indicates that a digital clock should  display  the
               time  in  twenty-four  hour format.  This is the default when a
               digital clock is 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.   This  option  is  effectively
               ignored when Xrender is in use.

       -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.   This  option  is effectively ignored when
               Xrender is in use.

       -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.

       -render This option tells xclock to use the Xrender extension  to  draw
               an  anti-aliased  face.  This is the default if xclock has been
               compiled with Xrender support.  Note that the  color  selection
               options  and  resources  used  when Xrender is in effect differ
               from the standard options.

       -norender
               This option turns off the use of Xrender to draw the clock.

       -sharp  This option tells xclock to use sharper edges when drawn  using
               the Xrender extension.

       -face pattern
               This  option specifies the font to use in digital mode when the
               Xrender extension is used.  Patterns are  specified  using  the
               fontconfig  face  format described in the Font Names section of
               fonts.conf(5).

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 tick 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.  Note that this resource  is  not  used  when
               Xrender is in effect.

       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.  Note that this resource is not used when Xrender is  in
               effect.

       analog (class Boolean)
               Specifies whether or not an analog clock should be used instead
               of a digital one.  The default is True.

       twentyfour (class Boolean)
               Specifies whether or not a digital  clock  should  display  the
               time in twenty-four hour format.  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.   This  font  is  only  used  when Xrender is not in
               effect.

       render (class Boolean)
               Specifies whether or not the Xrender extension should  be  used
               for  the  display.  The  default  is  True  if  xclock has been
               compiled with Xrender support.

       When Xrender is in  effect,  the  following  additional  resources  are
       understood:

       face (class FaceName)
               Specify  the  pattern  for  the font to be used for the digital
               clock when Xrender is used.   Patterns are specified using  the
               fontconfig  face  format described in the Font Names section of
               fonts.conf(5).

       sharp (class Boolean)
               Specifies if sharp edges should  be  used  when  rendering  the
               clock.  The default is False.

       buffer (class Boolean)
               Specifies  that  the updates of the image are drawn to a pixmap
               before copied into the window instead  drawing  them  into  the
               window directly.

       The  defaults  of  the  following  color  resources  depend  on whether
       reverseVideo is specified.  If reverseVideo is specified the default is
       lwhite, otherwise the default is black.

       hourColor (class Foreground)
               The color of the hour hand.

       minuteColor (class Foreground)
               The color of the minute hand.

       secondColor (class Foreground)
               The color of the second hand.

       majorColor (class Foreground)
               The color of the major scale ticks (i. e. each five minutes).

       minorColor (class Foreground)
               The color of the minor scale ticks (between major ticks).

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.
