DESCRIPTION
The watch command creates a watch with hour, minute, and
second hands modifying the time value.
METHODS
The watch command creates a new Tcl command whose
name is pathName. This command may be used to invoke various
operations on the widget. It has the following general form:
pathName option ?arg arg ...?
Option and the args
determine the exact behavior of the command. The following
commands are possible for watch widgets:
WIDGET-SPECIFIC METHODS
-  pathName cget option
-  Returns the current value of the configuration option given
by option.
Option may have any of the values accepted by the watch
command.
-  pathName configure ?option? ?value option value ...?
-  Query or modify the configuration options of the widget.
If no option is specified, returns a list describing all of
the available options for pathName (see Tk_ConfigureInfo for
information on the format of this list).  If option is specified
with no value, then the command returns a list describing the
one named option (this list will be identical to the corresponding
sublist of the value returned if no option is specified).  If
one or more option-value pairs are specified, then the command
modifies the given widget option(s) to have the given value(s);  in
this case the command returns an empty string.
Option may have any of the values accepted by the watch
command.
-  pathName get ?format?
-  Returns the current time of the watch in a format of 
string or as an integer clock value using the -string and -clicks
format options respectively.  The default is by string.  Reference the 
clock command for more information on obtaining time and its 
formats.
-  pathName show time
-  Changes the currently displayed time to be that of the time 
argument.  The time may be specified either as a string, an
integer clock value or the keyword "now".  Reference the clock 
command for more information on obtaining time and its format.
-  pathName watch ?args?
-  Evaluates the specifieds args against the canvas component.
