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 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.
X Version 11 Last change: xclock 1.0.7 1
User Commands XCLOCK(1)
-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. Patterns
are specified using the fontconfig face format
described in the Font Names section of
fonts.conf(4).
X DEFAULTS
This program uses the Clock widget. It understands all of
the core resource names and classes as well as:
X Version 11 Last change: xclock 1.0.7 2
User Commands XCLOCK(1)
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 dis-
play 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.
X Version 11 Last change: xclock 1.0.7 3
User Commands XCLOCK(1)
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(4).
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 spec-
ified 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 nota-
tion 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
/usr/share/X11/app-defaults/XClock

BUGS
Xclock believes the system clock.
When in digital mode, the string should be centered automat-
ically.
