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.

FILES

       /etc/X11/app-defaults/XClock
              specifies required resources

BUGS

       Xclock believes the system clock.

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