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.
l    Toggles the language attribute (French
    or English).
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

width (class Width)

The number of milliseconds of delay between iterations of fading.
seconds (class Boolean)
Specifies whether the seconds should be displayed or not.

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.
language (class String)
Specifies the language used to display the date (French or English).
alarm_snd (class String)
Only available on Sun Sparc stations. Specifies the full path of the sound played when alarm goes off. If set to Bell, defaults to the beep of the station.

Bugs

Dclock believes the system clock.

Scrolling from 9 to 10 O'Clock seems weird, but chances are you won't notice it.

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.
