DCLOCK(1) X Version 11(1 March 1988) DCLOCK(1)
NAME
dclock - digital clock for X
SYNOPSIS
dclock [-toolkitoption ...] [-option ...]
DESCRIPTION
The dclock program displays the time in digital format only. The time is
updated on a per second basis or on a per minute basis. This program is
nothing more than a wrapper around the dclock widget not associated with
any particular widget set.
When the clock is running, the user may change attributes by typing:
r Toggles Reverse Video.
s Toggles the seconds display.
b Toggles the bell attribute.
j Toggles the jump/scroll attribute.
f Toggles the fade attribute.
d Toggles the date format.
m Toggles the military time format.
a Toggles the alarm clock.
t Toggles the tails attribute.
q quit the program.
The third mouse button puts the clock in the mode where the alarm clock
can be set. The alarm must be set in 24-hour format to distringuish
between am and pm time. Digits can be changed by selecting the digit
with the left or middle mouse button. The Left button advances the time
while the Middle button moves the time backwards. Using the left or
middle button over the text at the bottom of the clock toggles the alarm
from actually being set (or, use the 'a' key).
OPTIONS
Dclock accepts all of the standard X Toolkit command line options along
with the additional options listed below:
-help This option indicates that a brief summary of the allowed options
should be printed on the standard error.
-bell This option indicates that the bell will beep once on the half
hour and twice on the hour.
-miltime
This option causes the clock to display the time in 24 hour
(military) time format.
-tails This option puts "tails" on the digits 6 and 9.
-scroll

-noscroll
When the time changes, the digits scroll from the previous digit
to the next digit. Since this is on by default, the -noscroll
option can turn it off.
-fade This option causes the display to fade from one digit to the next
instead of jumping or scrolling. If fade is specified, the
scroll attribute will be forced to off.
-fadeRate n
The fadeRate attribute takes an integer value which specifies the
number of milliseconds to wait between iterations when fading
from one digit to the next. A larger value will make the fade
slower and more pronounced. The default is 50.
-date format""
The date is printed under the time in the specified font. The
string displayed is in the "format" argument. If the string
contains a formatting character (%), then the next character is
examined and a value is inserted into the string. Example:
dclock -date "Today is %W"
The date string will print "Today is Friday" if the weekday name
happens to be friday. The formatting characters that are
understood are:
%W Full weekday name
%w Three-char weekday name (Sun, Mon, Tue...)
%M Full month name
%m Three-char month name (Jan, Feb, Mar...)
%d The date (numerical day number of the month)
%Y Full year (4 digits)
%y 2-digit year number
-alarm
-noalarm
The alarm is turned on or off. Alarm rings bell and toggles the
reverse video five times.
-alarmTime HH:MM
If alarm is set, it goes off at time specified in 24-hour format.
-seconds
This option will update the clock every second and display the
time including the seconds.
-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 ``Fixed.''
-rv This option indicates that reverse video should be simulated by
swapping the foreground and background colors.
-geometry geometry
This option specifies the prefered 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. This is
especially useful for setting resources that do not have separate
command line options.
X DEFAULTS
It understands all of the core resource names and classes as well as:
width (class Width)
Specifies the width of the clock.
height (class Height)
Specifies the height of the clock.
foreground (class Foreground)
Specifies the color for the tic marks. Using the class specifies
the color for all things that normally would appear in the
foreground color. The default is ``black'' since the core
default for background is ``white.''
bell (class Boolean)
Specifies whether or not a bell should be rung on the hour and
half hour.

Specifies that the foreground and background colors should be
reversed.
scroll (class Boolean)
Specifies whether the digits should scroll or not.
fade (class Boolean)
Specifies whether the digits should fade or not.
fadeRate (class Time)
The number of milliseconds of delay between iterations of fading.
seconds (class Boolean)
Specifies whether the seconds should be displayed or not.
bell (class Boolean)
Specifies whether the bell should sound on the half hour and on
the hour.
tails (class Boolean)
Specifies whether tails should be put on the digits 6 and 9.
alarm (class Boolean)
Specifies whether the alarm should go off at the specified time
(alarmTime).
alarmTime (class String)
Specifies the time alarm goes off if alarm is set.
ENVIRONMENT
DISPLAY to get the default host and display number. XENVIRONMENT to get
the name of a resource file that overrides the global resources
stored in the RESOURCE_MANAGER property.
SEE ALSO

BUGS
Dclock believes the system clock.
Scrolling from 9 to 10 O'Clock seems weird, but chances are you won't
notice it.

DCLOCK(1) X Version 11(1 March 1988) DCLOCK(1)
If the window is too small, the seconds are tough to read. This should
be recognized by the program and should display seconds using a font
rather than the bitmaps used by the clock itself.
