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. This is only effective for the
brief display.
-twentyfour This option indicates that a digital clock should display the
time in twenty-four hour format. This is only effective for
the brief display. 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

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 specifies required resources

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