+.SH DESCRIPTION
+The
+.I 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.
+.SH OPTIONS
+.I Xclock
+accepts all of the standard X Toolkit command line options along with the
+additional options listed below:
+.TP 8
+.B \-help
+This option indicates that a brief summary of the allowed options should be
+printed on the standard error.
+.TP 8
+.B \-analog
+This option indicates that a conventional 12 hour clock face with tick marks
+and hands should be used. This is the default.
+.TP 8
+\fB\-digital\fP or \fB\-d\fP
+This option indicates that a 24 hour digital clock should be used.
+.TP 8
+\fB\-brief\fP
+This option indicates that the digital clock should only display the hours
+and minutes fields. The default is to show the full time and date information.
+.TP 8
+\fB\-utime\fP
+This option indicates that a digital clock should display seconds since
+the Epoch (in format '970012340 seconds since Epoch' instead of a standard
+24-hour time.
+.TP 8
+.B \-strftime \fIformat\fP
+This option allows an strftime(__libmansuffix__) format string to be specified
+for the digital clock's display.
+.TP 8
+.B \-twelve
+This option indicates that a digital clock should display the time in
+twelve hour format.
+.TP 8
+.B \-twentyfour
+This option indicates that a digital clock should display the time in
+twenty-four hour format. This is the default when a digital clock is used.
+.TP 8
+.B \-chime
+This option indicates that the clock should chime
+once on the half hour and twice on the hour.
+.TP 8
+\fB\-hands\fP \fIcolor\fP (or \fB\-hd\fP \fIcolor\fP)
+This option specifies the color of the hands on an analog clock. The default
+is \fIblack\fP.
+This option is effectively ignored when Xrender is in use.
+.TP 8
+\fB\-highlight\fP \fIcolor\fP (or \fB\-hl\fP \fIcolor\fP)
+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 \fIblack\fP.
+This option is effectively ignored when Xrender is in use.
+.TP 8
+.B \-update \fIseconds\fP
+This option specifies the frequency in seconds at which \fIxclock\fP
+should update its display. If the clock is obscured and then exposed,
+it will be updated immediately. A value of 30 seconds or less will enable a
+second hand on an analog clock. The default is 60 seconds.
+.TP 8
+.B \-padding \fInumber\fP
+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.
+.TP 8
+.B \-render
+This option tells \fIxclock\fP to use the Xrender extension to draw an
+anti-aliased face. This is the default if \fIxclock\fP has been
+compiled with Xrender support.
+Note that the color selection options and resources used when Xrender is
+in effect differ from the standard options.
+.TP 8
+.B \-norender
+This option turns off the use of Xrender to draw the clock.
+.TP 8
+.B \-sharp
+This option tells \fIxclock\fP to use sharper edges when drawn using
+the Xrender extension.
+.TP 8
+.B \-face \fIpattern\fP
+This option specifies the font to use in digital mode when the
+Xrender extension is used. Patterns are specified using the
+fontconfig face format described in the
+.I Font Names
+section of
+.IR fonts.conf (__filemansuffix__).
+.SH X DEFAULTS
+This program uses the
+.I Clock
+widget. It understands all of the core resource names and classes as well as:
+.PP
+.TP 8
+.B width (\fPclass\fB 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.
+.TP 8
+.B height (\fPclass\fB 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.
+.TP 8
+.B update (\fPclass\fB Interval)
+Specifies the frequency in seconds at which the time should be redisplayed.
+.TP 8
+.B foreground (\fPclass\fB Foreground)
+Specifies the color for the tick marks. The default depends on whether
+\fIreverseVideo\fP is specified. If \fIreverseVideo\fP is specified
+the default is \fIlwhite\fP, otherwise the default is \fIblack\fP.
+
+.TP 8
+.B hands (\fPclass\fB Foreground)
+Specifies the color of the insides of the clock's hands. The default
+depends on whether
+\fIreverseVideo\fP is specified. If \fIreverseVideo\fP is specified
+the default is \fIlwhite\fP, otherwise the default is \fIblack\fP.
+Note that this resource is not used when Xrender is in effect.
+.TP 8
+.B highlight (\fPclass\fB Foreground)
+Specifies the color used to highlight the clock's hands. The default is
+ depends on whether
+\fIreverseVideo\fP is specified. If \fIreverseVideo\fP is specified
+the default is \fIlwhite\fP, otherwise the default is \fIblack\fP.
+Note that this resource is not used when Xrender is in effect.
+.TP 8
+.B analog (\fPclass\fB Boolean)
+Specifies whether or not an analog clock should be used instead of a digital
+one. The default is True.
+.TP 8
+.B twentyfour (\fPclass\fB Boolean)
+Specifies whether or not a digital clock should display the time in
+twenty-four hour format. The default is True.
+.TP 8
+.B chime (\fPclass\fB Boolean)
+Specifies whether or not a bell should be rung on the hour and half hour.
+.TP 8
+.B padding (\fPclass\fB Margin)
+Specifies the amount of internal padding in pixels to be used. The default is
+8.
+.TP 8
+.B font (\fPclass\fB Font)

+fonts currently will not always display correctly.
+This font is only used when Xrender is not in effect.
+.TP 8
+.B render (\fPclass\fB Boolean)
+Specifies whether or not the Xrender extension should be used for the
+display. The default is True if \fIxclock\fP has been compiled with
+Xrender support.
+.PP
+When Xrender is in effect, the following additional resources are
+understood:
+.PP
+.TP 8
+.B face (\fPclass\fB FaceName)
+Specify the pattern for the font to be used for the digital clock when
+Xrender is used. Patterns are specified using the fontconfig face format
+described in the
+.I Font Names
+section of
+.IR fonts.conf (__filemansuffix__).
+.TP 8
+.B sharp (\fPclass\fB Boolean)
+Specifies if sharp edges should be used when rendering the clock.
+The default is False.
+.TP 8
+.B buffer (\fPclass\fB Boolean)
+Specifies that the updates of the image are drawn to a pixmap before copied
+into the window instead drawing them into the window directly.
+.PP
+The defaults of the following color resources depend on whether
+\fIreverseVideo\fP is specified.
+If \fIreverseVideo\fP is specified the default is \fIlwhite\fP,
+otherwise the default is \fIblack\fP.

+The color of the major scale ticks (i. e. each five minutes).
+.TP 8
+.B minorColor (\fPclass\fB Foreground)
+The color of the minor scale ticks (between major ticks).
+.SH WIDGETS
+In order to specify resources, it is useful to know the hierarchy of
+the widgets which compose \fIxclock\fR. In the notation below,
+indentation indicates hierarchical structure. The widget class name
+is given first, followed by the widget instance name.
