xclock

SYNOPSIS

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

The xclock(1) program displays the time in analog or digital form. The time is continuously updated at a frequency that can be specified by the user. This program is nothing more than a wrapper around the Athena Clock widget.

OPTIONS

The xclock(1) utility accepts all of the standard X Toolkit command-line options, along with the additional following options:

-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. If both -analog and -digital are specified, the last one on the command line takes effect.
-chime: This option indicates that the clock should chime once on the half hour and twice on the hour.
-digital: This option indicates that a 24-hour digital clock should be used. If both -analog and -digital are specified, the last one on the command line takes effect.
-hd color: This option specifies the color of the hands on an analog clock. The default is black.
-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.
-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.
-update seconds: This option specifies the frequency in seconds at which xclock(1) should update its display. If the clock is obscured and then exposed, it will be updated immediately. A value of less than 30 seconds will enable a second hand on an analog clock. The default is 60 seconds.

X DEFAULTS

This program uses the Athena Clock widget. It understands all of the core resource names and classes as well as the following:

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 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 a bell should be rung on the hour and half hour.
padding (classMargin): Specifies the amount of internal padding in pixels to be used. The default is 8.
font (classFont): 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 that compose xclock(1). In the notation below, indentation indicates hierarchical structure. The widget class name is given first, followed by the widget instance name.

  Clock  clock

ENVIRONMENT VARIABLES

DISPLAY: Contains the default host and display number.
XENVIRONMENT: Contains the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.

FILES

/usr/lib/X11/app-defaults/XClock: Specifies required resources.

BUGS

The xclock(1) believes the system clock.

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