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.
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)
.
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).
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.

Clock clock
- 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.
- /usr/share/X11/app-defaults/XClock
- specifies required resources

.
Xclock believes the system clock.
When in digital mode, the string
should be centered automatically.
