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.
- -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.
- -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.
- -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.
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 tic marks. The
default is 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 is depends on whether reverseVideo is specified. If reverseVideo
is specified the default is lwhite, otherwise the default is black.
- 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.
- analog (class Boolean)
- Specifies
whether or not an analog clock should be used instead of a digital one.
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.
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.

- 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.
<XRoot>/lib/X11/app-defaults/XClock
- specifies required resources

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