XCLOCK(1X11) COMMAND REFERENCE XCLOCK(1X11) NAME xclock - analog / digital clock for X SYNOPSIS xclock [-toolkitoption ...] [-option ...] This is a user-contributed client. DESCRIPTION The xclock program displays the time in analog or digital form. The time is continuously updated at a frequency which may be specified by the user. This program is nothing more than a wrapper around the Athena Clock widget. OPTIONS This program accepts all standard X Toolkit command line options along with the additional options listed here: -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. -digital This option indicates that a 24 hour digital clock should be used. -chime This option indicates that the clock should chime once on the half hour and twice on the hour. -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. -update seconds This option specifies the frequency in seconds at which xclock 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. -padding number This option specifies the width in pixels of Printed 3/22/89 1
XCLOCK(1X11) COMMAND REFERENCE XCLOCK(1X11) 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 This option specifies the color to use for the background of the window. The default is white. -bd color This option specifies the color to use for the border of the window. The default is black. -bw number This option specifies the width in pixels of the border surrounding the window. -fg color This option specifies the color to use for displaying text. The default is black. -fn font This option specifies the font to be used for displaying normal text. The default is 6x10. -rv This option indicates that reverse video should be simulated by swapping the foreground and background colors. -geometry geometry This option specifies the preferred size and position of the clock window. -display host:display This option specifies the X server to contact. -xrm resourcestring This option specifies a resource string to be used. X DEFAULTS This program uses the Clock widget in the X Toolkit. It understands all of the core resource names and classes as well as the commands listed here. 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 Printed 3/22/89 2
XCLOCK(1X11) COMMAND REFERENCE XCLOCK(1X11) 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 be rung 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 variable width fonts currently will not always Printed 3/22/89 3
XCLOCK(1X11) COMMAND REFERENCE XCLOCK(1X11) display correctly. reverseVideo (class ReverseVideo) Specifies that the foreground and background colors should be reversed. CAVEATS The xclock program 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 will be quietly ignored. A negative offset of less than 1 hour is treated as a positive offset. Digital clock windows default to the analog clock size. Border color has to be explicitly specified when reverse video is used. SEE ALSO X(1x11), xrdb(1x11), and time(3C).
