actually,I would like for the text to change to the time upon pressing the button

If you want to change the system time, you need to use the "exec" command. That makes it system dependant. What is the syntax for changing the time on your system?

actually what I want to happen, is when I depress the button that displays "press button for time",I want the time to appear in its place.

Ah. You use "configure" for that. Here's what I would do, starting from what you have:

button .b -text "press button for time" -command [red]btime[/red]
pack .b
[red]proc btime {} {
set tnow [clock seconds]
set tstr [clock format $tnow -format "%x %T"]
.b configure -text $tstr
}
[/red]

I don't know of any for Tcl, itself, other than the help pages that come with the installation. I find them to be very instructive. As for Tk, I recommend the demos that are installed with ActiveState. You can look at all the code that runs them.
