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 informa-
             tion.

     -utime or -d
             This option indicates that a digital clock should
             display seconds since the Epoch (in format
             '970012340 seconds since Epoch' instead of a stan-
             dard 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 exten-
             sion 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.

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

XCLOCK(1)           UNIX Programmer's Manual            XCLOCK(1)

             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.

     sharp (class Boolean)
             Specifies if sharp edges should be used when render-
             ing 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 draw-
             ing them into the window directly.

     The defaults of the following color resources depend on
     whether reverseVideo is specified. If reverseVideo is speci-
     fied 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).
