14 The xclock program displays the time in analog or digital form. The
15 time is continuously updated at a frequency which may be specified by
16 the user.
17
19 Xclock accepts all of the standard X Toolkit command line options along
20 with the additional options listed below:
21 -help This option indicates that a brief summary of the allowed
23 options should be printed on the standard error.
24 -analog This option indicates that a conventional 12 hour clock face
26 with tick marks and hands should be used. This is the default.
27 -digital or -d
29 This option indicates that a 24 hour digital clock should be
30 used.
31 -brief This option indicates that the digital clock should only dis‐
33 play the hours and minutes fields. The default is to show the
34 full time and date information.
35 -utime or -d
37 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.
94
96 This program uses the Clock widget. It understands all of the core
97 resource names and classes as well as:
98 width (class Width)
100 Specifies the width of the clock. The default for analog
101 clocks is 164 pixels; the default for digital clocks is what‐
102 ever is needed to hold the clock when displayed in the chosen
103 font.
104 height (class Height)
106 Specifies the height of the clock. The default for analog
107 clocks is 164 pixels; the default for digital clocks is what‐
108 ever is needed to hold the clock when displayed in the chosen
109 font.
110 update (class Interval)
112 Specifies the frequency in seconds at which the time should be
113 redisplayed.
114 foreground (class Foreground)
116 Specifies the color for the tick marks. The default depends on
117 whether reverseVideo is specified. If reverseVideo is speci‐
118 fied the default is lwhite, otherwise the default is black.
119 hands (class Foreground)
122 Specifies the color of the insides of the clock's hands. The
123 default depends on whether reverseVideo is specified. If
124 reverseVideo is specified the default is lwhite, otherwise the
125 default is black. Note that this resource is not used when
126 Xrender is in effect.
127 highlight (class Foreground)
129 Specifies the color used to highlight the clock's hands. The
130 default is
131 depends on whether reverseVideo is specified. If reverseVideo
132 is specified the default is lwhite, otherwise the default is
133 black. Note that this resource is not used when Xrender is in
134 effect.
135 analog (class Boolean)
137 Specifies whether or not an analog clock should be used instead
138 of a digital one. The default is True.
139 twentyfour (class Boolean)
141 Specifies whether or not a digital clock should display the
142 time in twenty-four hour format. The default is True.
143 chime (class Boolean)
145 Specifies whether or not a bell should be rung on the hour and
146 half hour.
147 padding (class Margin)
149 Specifies the amount of internal padding in pixels to be used.
150 The default is 8.
151 font (class Font)
153 Specifies the font to be used for the digital clock. Note that
154 variable width fonts currently will not always display cor‐
155 rectly. This font is only used when Xrender is not in effect.
156 render (class Boolean)
158 Specifies whether or not the Xrender extension should be used
159 for the display. The default is True if xclock has been com‐
160 piled with Xrender support.
161 When Xrender is in effect, the following additional resources are
163 understood:
164 face (class FaceName)
166 Specify the pattern for the font to be used for the digital
167 clock when Xrender is used.
168 sharp (class Boolean)
170 Specifies if sharp edges should be used when rendering the
171 clock. The default is False.
172 buffer (class Boolean)
174 Specifies that the updates of the image are drawn to a pixmap
175 before copied into the window instead drawing them into the
176 window directly.
177 The defaults of the following color resources depend on whether rever‐
179 seVideo is specified. If reverseVideo is specified the default is
180 lwhite, otherwise the default is black.
181 hourColor (class Foreground)
183 The color of the hour hand.
184 minuteColor (class Foreground)
186 The color of the minute hand.
187 secondColor (class Foreground)
189 The color of the second hand.
190 majorColor (class Foreground)
192 The color of the major scale ticks (i. e. each five minutes).
193 minorColor (class Foreground)
195 The color of the minor scale ticks (between major ticks).
196
198 In order to specify resources, it is useful to know the hierarchy of
199 the widgets which compose xclock. In the notation below, indentation
200 indicates hierarchical structure. The widget class name is given
201 first, followed by the widget instance name.
202 XClock xclock
204 Clock clock
205
208 DISPLAY to get the default host and display number.
209 XENVIRONMENT
211 to get the name of a resource file that overrides the global
212 resources stored in the RESOURCE_MANAGER property.
213
215 /usr/share/X11/app-defaults/XClock
216 specifies required resources
217
219 X(7), xrdb(1), time(3C)
220
222 Xclock believes the system clock.
223 When in digital mode, the string should be centered automatically.
