SWISSWATCH(1)SWISSWATCH(1)NAMEswisswatch - the mother of all X Toolkit clocks
SYNOPSISswisswatch [-option ...]
DESCRIPTION
Swisswatch is an analog clock for X that is highly customizable by
means of resources.
SYNOPSIS
Handles minute-hand display correctly when ticking more often than once
a minute.
Handles arbitrary number of hands and/or mark specifications.
OPTIONS-fg foreground color
choose a different color for the hands and marks.
-bg background color
choose a different color for the background.
-tick time
the interval between updates of the display. This should be a
positive floating-point number. -geometry geometry define the
initial window geometry; see X(1).
-display display
specify the display to use; see X(1).
-noshape
causes the clock to not reshape itself and ancestors to exactly
fit the outline of the clock.
-railroad
-sbb
-cff
-ffs causes the second and minute hands to behave differently at the
turn of the minute. This mode tries to mimick the Look and
Feel of the swiss federal railway clocks.
RESOURCES
.tickTime / .TickTime
Time between ticks, in seconds. The hands will move this
often. (All hands have their positions recomputed and redrawn
each time the clock ticks.) This is a floating-point value,
though values less than the system's clock resolution will not
work very well. Ticks occur precisely on the appropriate bound‐
ary, regardless of when the program was started; for example,
if tickTime is 5, ticks occur precisely when gettimeof‐
day().tv_sec%5 changes.
.numMarks / .NumMarks
Number of sets of marks around the clock face.
.child_n.cycle / .Mark.Cycle / .Hand.Cycle
For a mark, the number of marks in set n. For a hand, the num‐
ber of ticks corresponding to one complete turn of the hand.
.child_n.outsideEnd / .Mark.OutsideEnd
Outside end of marks in set n, as a radial distance.
.child_n.length / .Mark.Length
Length of marks in set n; the marks extend from the outsideEnd
position inward for this distance.
.child_n.phase / .Mark.Phase
Phase of mark set n. This specifies a rotation of the whole
set of marks. The default is 0, which specifies that a mark
appear at the straight-up ("12-o'clock") position, with the
other number-1 marks (if any) spaced evenly around the face.
If phase is nonzero, it specifies a rotation of the entire set
of marks clockwise. The value is the rotation, as a fraction
of the distance from one mark to the next. For example, any
integer value will have no visible effect (any desired effect
corresponds to some value in [0..1]). Experimentation is rec‐
ommended.
.child_n.centerX / .Mark.CenterX
.child_n.centerY / .Mark.CenterY
These specify where on the clock face the center of the circle
formed by the marks is to be. The X and Y coordinates are
scaled so that the bounding square of the clock face is [-1..1]
x [-1..1]. This allows for placing circles of marks centered
at points other than the center of the clock face; this is use‐
ful primarily in conjunction with the corresponding options for
hands.
.child_n.foreground / .Mark.Foreground
Color used to draw a mark or hand.
.nChildren / .NChildren
Number of hands and marks on the clock.
.child_n.class
The class of the hand or mark, currently only "Hand" and "Mark"
are supported.
.child_n.width / .Hand.Width
The width of the hand. For triangular hands, this is the width
of the base; for rectangular hands, this is the width of the
rectangle; and for circular hands, this is the diameter of the
circle. If the width of a triangular or rectangular outline
hand is zero, the hand is drawn as a single line instead of the
full shape.
.child_n.shape / .Hand.Shape
The shape of the hand. Hands can be triangular, rectangular,
or circular; the allowed values are "triangle", "rectangle",
"circle", "triangular", "rectangular", and "circular". Illegal
values produce a complaint and a default is used.
.child_n.render / .Hand.Render
The rendition of the hand. Hands can be drawn as outlines or
as filled shapes; the allowed values are "outline", "fill",
"outlined", and "filled". Illegal values produce a complaint
and a default is used.
.child_n.strokeWidth / .Hand.StrokeWidth
The width of strokes used to draw the hand, when the hand is
drawn in a way that uses strokes. A value of 0 uses so-called
"thin" lines, which are often faster.
.child_n.strokeWidthR / .Hand.StrokeWidthR
If a non-zero floating point number is specified, the stroke
width will always be the product of this number and the clock's
outer radius (in x direction if it is an ellipsis).
.child_n.cap / .Hand.Cap
The line cap style used when drawing hands. This produces no
visual effect except when drawing triangular or rectangular
hands of width 0. Legal values are "notlast", "butt", "round",
"projecting", "capnotlast", "capbutt", "capround", and "cappro‐
jecting".
.child_n.join / .Hand.Join
The line join style used when drawing hands. Legal values are
"miter", "round", "bevel", "joinmiter", joinround", and "join‐
bevel".
.child_n.cycle / .Hand.Cycle
The number of seconds it takes for the hand to circle around
the face once. For example, a normal second hand will give 60,
a normal minute hand 3600. If this is small compared to the
tickTime value, the hand will move by visually large amounts
each tick; this may or may not be desirable. The value may be
floating-point.
.child_n.phase / .Hand.Phase
An offset applied to the time of day before computing the hand
position. To determine the position of a hand, the following
is computed:
((now - tz - phase) % cycle) / cycle
where `now' is the current time of day (obtained with time(3)),
tz is a correction factor for the timezone as found in the
tm_gmtoff field of the structure returned by localtime(3)),
phase is the value of the phase resource for the hand, and
cycle is the value of the cycle resource for the hand. The
result is a number from 0 to 1, which is mapped into an angular
position, with 0 being straight up, .25 being straight right,
.5 being straight down, etc.
The simplest way to determine the desired phase value for a
hand is to experiment. It is usually obvious that the value
should be a multiple of something like 3600; try various multi‐
ples until you get the desired hand position.
.child_n.color / .Hand.Foreground
The color used for drawing the hand. Hands are drawn opaquely
in increasing numerical order.
.child_n.center.x / .Hand.Center.X
.child_n.center.y / .Hand.Center.Y
These specify where on the clock face the pivot point of the
hand is to be. The X and Y coordinates are scaled so that the
bounding square of the clock face is 1..1] x [-1..1]. This
allows hands to rotate about points other than the center of
the clock face, as with some watches.
.geometry / .Geometry
Geometry specification, when none is given on the command line.
If no geometry spec can be found anywhere, the equivalent of
200x200+100+100 is used.
.background / .Background
Color used as a background for all drawing.
.name / .Name
A string, which is stored as the window manager name for the
window. If none is given, "xwatch" is used.
.iconName / .IconName
A string, which is stored as the window manager icon name for
the window. If none is given, "xwatch" is used.
.railroad / .Railroad
Enables or disables Swiss-railway-clock mode, as described
under the -railroad command-line option. The value can be
"true", "false", "yes", or "no".
.circular / .Circular
If set, the clock will remain circular even if one tries to
resize it to a non-circular ellipse. This is the previous
behavior. The possible values are the same as for
.swiss/.Swiss.
EXAMPLE RESOURCES
The distributed application defaults files define three different looks
for swisswatch. Try them out by calling it as
swisswatch
swisswatch -name swissclock
swisswatch-name oclock
COLORS
If you would like your clock to be viewable in color, include the fol‐
lowing in the #ifdef COLOR section you read with xrdb:
*customization: -color
This will cause swisswatch to pick up the colors in the app-defaults
color customization file: /usr/lib/X11/app-defaults/SwissWatch-color.

CREDITS
Der Mouse <mouse@larry.McRCIM.McGill.EDU> wrote the mclock program that
already featured most of the functionality: smooth movement of the
minute hand and excessive configurability. I basically reimplemented
mclock as a Toolkit application. This manpage also contains slightly
adapted text from mclock.doc.
