NAME
xclock - analog / digital clock for X

SYNOPSIS
xclock [ -help ] [ -analog ] [ -digital ] [ -chime ] [ -hd
color ] [ -hl color ] [ -update seconds ] [ -padding number
]

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.

-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.

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 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 reverseVi-
deo 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.

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.

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

BUGS
Xclock believes the system clock.

When in digital mode, the string should be centered automat-
ically.
