NAME
xclock - analog / digital clock for X
SYNOPSIS
xclock [-toolkitoption ...] [-option ...]
DESCRIPTION
The xclock program displays the time in analog or
digital form. The time is continuously updated at a
frequency that the user may specify. This program is
nothing more than a wrapper around the Athena Clock
widget.
OPTIONS
xclock accepts all of the standard X Toolkit command
line options in addition to the following:
-help
indicates that a brief summary of the allowed
options should be printed on the standard error.
-analog
indicates that a conventional 12-hour clock face
with tick marks and hands should be used. This is
the default.
-digital
indicates that a 24-hour digital clock should be
used.
-chime
indicates that the clock should chime once on the
half hour and twice on the hour.
-hd color
specifies the color of the hands on an analog
clock. The default is black.
-hl color
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
specifies the frequency in seconds at which xclock
should update its display. If the clock is
obscured and then exposed, it is updated
immediately. A value of less than 30 seconds
enables a second hand on an analog clock. The
default is 60.

-padding number
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.
The following standard X Toolkit command line arguments
are commonly used with xclock:
-bg color
specifies the color to use for the background of
the window. The default is white.
-bd color
specifies the color to use for the border of the
window. The default is black.
-bw number
specifies the width in pixels of the border
surrounding the window.
-fg color
specifies the color to use for displaying text.
The default is black.
-fn font
specifies the font to be used for displaying normal
text. The default is 6x10.
-rv
indicates that reverse video should be simulated by
swapping the foreground and background colors.
-geometry geometry
specifies the preferred size and position of the
clock window.
-display host:display
specifies the X server to contact.
-xrm resourcestring
specifies a resource string to be used.
X DEFAULTS
This program uses the Clock widget in the X Toolkit.
It understands all 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 black since the core default for background is
white.
hands (class Foreground)
specifies the color of the insides of the clock's
hands.
highlight (class Foreground)
specifies the color used to highlight the clock's
hands.
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 ring 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 currently, variable width fonts
will not always display correctly.
reverseVideo (class ReverseVideo)
specifies that the foreground and background colors
should be reversed.

BUGS
xclock believes the system clock.
When in digital mode, the string should be centered
automatically.
When specifying a time offset, the grammar requires an
hours field but if only minutes are given, they are
quietly ignored. A negative offset of less than 1 hour
is treated as a positive offset.
Border color has to be explicitly specified when
reverse video is used.
