15 The xclock program displays the time in analog or digital form. The
16 time is continuously updated at a frequency which may be specified by
17 the user.
18
20 Xclock accepts all of the standard X Toolkit command line options along
21 with the additional options listed below:
22 -help This option indicates that a brief summary of the allowed
24 options should be printed on the standard error.
25 -analog This option indicates that a conventional 12 hour clock face
27 with tick marks and hands should be used. This is the default.
28 -digital or -d
30 This option indicates that a 24 hour digital clock should be
31 used.
32 -brief This option indicates that the digital clock should only dis‐
34 play the hours and minutes fields. The default is to show the
35 full time and date information.
36 -utime This option indicates that a digital clock should display sec‐
38 onds since the Epoch (in format '970012340 seconds since Epoch'
39 instead of a standard 24-hour time.
40 -strftime format
42 This option allows an strftime(3) format string to be specified
43 for the digital clock's display.
44 -twelve This option indicates that a digital clock should display the
46 time in twelve hour format.
47 -twentyfour
49 This option indicates that a digital clock should display the
50 time in twenty-four hour format. This is the default when a
51 digital clock is used.
52 -chime This option indicates that the clock should chime once on the
54 half hour and twice on the hour.
55 -hands color (or -hd color)
57 This option specifies the color of the hands on an analog
58 clock. The default is black. This option is effectively
59 ignored when Xrender is in use.
60 -highlight color (or -hl color)
62 This option specifies the color of the edges of the hands on an
63 analog clock, and is only useful on color displays. The
64 default is black. This option is effectively ignored when
65 Xrender is in use.
66 -update seconds
68 This option specifies the frequency in seconds at which xclock
69 should update its display. If the clock is obscured and then
70 exposed, it will be updated immediately. A value of 30 seconds
71 or less will enable a second hand on an analog clock. The
72 default is 60 seconds.
73 -padding number
75 This option specifies the width in pixels of the padding
76 between the window border and clock text or picture. The
77 default is 10 on a digital clock and 8 on an analog clock.
78 -render This option tells xclock to use the Xrender extension to draw
80 an anti-aliased face. This is the default if xclock has been
81 compiled with Xrender support. Note that the color selection
82 options and resources used when Xrender is in effect differ
83 from the standard options.
84 -norender
86 This option turns off the use of Xrender to draw the clock.
87 -sharp This option tells xclock to use sharper edges when drawn using
89 the Xrender extension.
90 -face pattern
92 This option specifies the font to use in digital mode when the
93 Xrender extension is used. Patterns are specified using the
94 fontconfig face format described in the Font Names section of
95 fonts.conf(5).
96
98 This program uses the Clock widget. It understands all of the core
99 resource names and classes as well as:
100 width (class Width)
102 Specifies the width of the clock. The default for analog
103 clocks is 164 pixels; the default for digital clocks is what‐
104 ever is needed to hold the clock when displayed in the chosen
105 font.
106 height (class Height)
108 Specifies the height of the clock. The default for analog
109 clocks is 164 pixels; the default for digital clocks is what‐
110 ever is needed to hold the clock when displayed in the chosen
111 font.
112 update (class Interval)
114 Specifies the frequency in seconds at which the time should be
115 redisplayed.
116 foreground (class Foreground)
118 Specifies the color for the tick marks. The default depends on
119 whether reverseVideo is specified. If reverseVideo is speci‐
120 fied the default is lwhite, otherwise the default is black.
121 hands (class Foreground)
124 Specifies the color of the insides of the clock's hands. The
125 default depends on whether reverseVideo is specified. If
126 reverseVideo is specified the default is lwhite, otherwise the
127 default is black. Note that this resource is not used when
128 Xrender is in effect.
129 highlight (class Foreground)
131 Specifies the color used to highlight the clock's hands. The
132 default is
133 depends on whether reverseVideo is specified. If reverseVideo
134 is specified the default is lwhite, otherwise the default is
135 black. Note that this resource is not used when Xrender is in
136 effect.
137 analog (class Boolean)
139 Specifies whether or not an analog clock should be used instead
140 of a digital one. The default is True.
141 twentyfour (class Boolean)
143 Specifies whether or not a digital clock should display the
144 time in twenty-four hour format. The default is True.
145 chime (class Boolean)
147 Specifies whether or not a bell should be rung on the hour and
148 half hour.
149 padding (class Margin)
151 Specifies the amount of internal padding in pixels to be used.
152 The default is 8.
153 font (class Font)
155 Specifies the font to be used for the digital clock. Note that
156 variable width fonts currently will not always display cor‐
157 rectly. This font is only used when Xrender is not in effect.
158 render (class Boolean)
160 Specifies whether or not the Xrender extension should be used
161 for the display. The default is True if xclock has been com‐
162 piled with Xrender support.
163 When Xrender is in effect, the following additional resources are
165 understood:
166 face (class FaceName)
168 Specify the pattern for the font to be used for the digital
169 clock when Xrender is used. Patterns are specified using the
170 fontconfig face format described in the Font Names section of
171 fonts.conf(5).
172 sharp (class Boolean)
174 Specifies if sharp edges should be used when rendering the
175 clock. The default is False.
176 buffer (class Boolean)
178 Specifies that the updates of the image are drawn to a pixmap
179 before copied into the window instead drawing them into the
180 window directly.
181 The defaults of the following color resources depend on whether rever‐
183 seVideo is specified. If reverseVideo is specified the default is
184 lwhite, otherwise the default is black.
185 hourColor (class Foreground)
187 The color of the hour hand.
188 minuteColor (class Foreground)
190 The color of the minute hand.
191 secondColor (class Foreground)
193 The color of the second hand.
194 majorColor (class Foreground)
196 The color of the major scale ticks (i. e. each five minutes).
197 minorColor (class Foreground)
199 The color of the minor scale ticks (between major ticks).
200
202 In order to specify resources, it is useful to know the hierarchy of
203 the widgets which compose xclock. In the notation below, indentation
204 indicates hierarchical structure. The widget class name is given
205 first, followed by the widget instance name.
206 XClock xclock
208 Clock clock
209
212 DISPLAY to get the default host and display number.
213 XENVIRONMENT
215 to get the name of a resource file that overrides the global
216 resources stored in the RESOURCE_MANAGER property.
217
219 /usr/share/X11/app-defaults/XClock
220 specifies required resources
221
223 X(7), xrdb(1), time(3), fonts.conf (5).
224
226 Xclock believes the system clock.
227 When in digital mode, the string should be centered automatically.
