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 op‐
24 tions 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. This is only effective for the
47 brief display.
48 -twentyfour
50 This option indicates that a digital clock should display the
51 time in twenty-four hour format. This is only effective for
52 the brief display. This is the default when a digital clock is
53 used.
54 -chime This option indicates that the clock should chime once on the
56 half hour and twice on the hour.
57 -hands color (or -hd color)
59 This option specifies the color of the hands on an analog
60 clock. The default is black. This option is effectively ig‐
61 nored when Xrender is in use.
62 -highlight color (or -hl color)
64 This option specifies the color of the edges of the hands on an
65 analog clock, and is only useful on color displays. The de‐
66 fault is black. This option is effectively ignored when Xren‐
67 der is in use.
68 -update seconds
70 This option specifies the frequency in seconds at which xclock
71 should update its display. If the clock is obscured and then
72 exposed, it will be updated immediately. A value of 30 seconds
73 or less will enable a second hand on an analog clock. The de‐
74 fault is 60 seconds.
75 -padding number
77 This option specifies the width in pixels of the padding be‐
78 tween the window border and clock text or picture. The default
79 is 10 on a digital clock and 8 on an analog clock.
80 -render This option tells xclock to use the Xrender extension to draw
82 an anti-aliased face. This is the default if xclock has been
83 compiled with Xrender support. Note that the color selection
84 options and resources used when Xrender is in effect differ
85 from the standard options.
86 -norender
88 This option turns off the use of Xrender to draw the clock.
89 -sharp This option tells xclock to use sharper edges when drawn using
91 the Xrender extension.
92 -face pattern
94 This option specifies the font to use in digital mode when the
95 Xrender extension is used. Patterns are specified using the
96 fontconfig face format described in the Font Names section of
97 fonts.conf(5).
98
100 This program uses the Clock widget. It understands all of the core re‐
101 source names and classes as well as:
102 width (class Width)
104 Specifies the width of the clock. The default for analog
105 clocks is 164 pixels; the default for digital clocks is what‐
106 ever is needed to hold the clock when displayed in the chosen
107 font.
108 height (class Height)
110 Specifies the height of the clock. The default for analog
111 clocks is 164 pixels; the default for digital clocks is what‐
112 ever is needed to hold the clock when displayed in the chosen
113 font.
114 update (class Interval)
116 Specifies the frequency in seconds at which the time should be
117 redisplayed.
118 foreground (class Foreground)
120 Specifies the color for the tick marks. The default depends on
121 whether reverseVideo is specified. If reverseVideo is speci‐
122 fied the default is lwhite, otherwise the default is black.
123 hands (class Foreground)
126 Specifies the color of the insides of the clock's hands. The
127 default depends on whether reverseVideo is specified. If re‐
128 verseVideo is specified the default is lwhite, otherwise the
129 default is black. Note that this resource is not used when
130 Xrender is in effect.
131 highlight (class Foreground)
133 Specifies the color used to highlight the clock's hands. The
134 default is
135 depends on whether reverseVideo is specified. If reverseVideo
136 is specified the default is lwhite, otherwise the default is
137 black. Note that this resource is not used when Xrender is in
138 effect.
139 analog (class Boolean)
141 Specifies whether or not an analog clock should be used instead
142 of a digital one. The default is True.
143 twentyfour (class Boolean)
145 Specifies whether or not a digital clock should display the
146 time in twenty-four hour format. The default is True.
147 chime (class Boolean)
149 Specifies whether or not a bell should be rung on the hour and
150 half hour.
151 padding (class Margin)
153 Specifies the amount of internal padding in pixels to be used.
154 The default is 8.
155 font (class Font)
157 Specifies the font to be used for the digital clock. Note that
158 variable width fonts currently will not always display cor‐
159 rectly. This font is only used when Xrender is not in effect.
160 render (class Boolean)
162 Specifies whether or not the Xrender extension should be used
163 for the display. The default is True if xclock has been com‐
164 piled with Xrender support.
165 When Xrender is in effect, the following additional resources are un‐
167 derstood:
168 face (class FaceName)
170 Specify the pattern for the font to be used for the digital
171 clock when Xrender is used. Patterns are specified using the
172 fontconfig face format described in the Font Names section of
173 fonts.conf(5).
174 sharp (class Boolean)
176 Specifies if sharp edges should be used when rendering the
177 clock. The default is False.
178 buffer (class Boolean)
180 Specifies that the updates of the image are drawn to a pixmap
181 before copied into the window instead drawing them into the
182 window directly.
183 The defaults of the following color resources depend on whether rever‐
185 seVideo is specified. If reverseVideo is specified the default is
186 lwhite, otherwise the default is black.
187 hourColor (class Foreground)
189 The color of the hour hand.
190 minuteColor (class Foreground)
192 The color of the minute hand.
193 secondColor (class Foreground)
195 The color of the second hand.
196 majorColor (class Foreground)
198 The color of the major scale ticks (i. e. each five minutes).
199 minorColor (class Foreground)
201 The color of the minor scale ticks (between major ticks).
202
204 In order to specify resources, it is useful to know the hierarchy of
205 the widgets which compose xclock. In the notation below, indentation
206 indicates hierarchical structure. The widget class name is given
207 first, followed by the widget instance name.
208 XClock xclock
210 Clock clock
211
214 DISPLAY to get the default host and display number.
215 XENVIRONMENT
217 to get the name of a resource file that overrides the global
218 resources stored in the RESOURCE_MANAGER property.
219
221 /usr/share/X11/app-defaults/XClock
222 specifies required resources
223
225 X(7), xrdb(1), time(3), fonts.conf (5).
226
228 Xclock believes the system clock.
229 When in digital mode, the string should be centered automatically.
