OK, but you dont need to use the command to toggle
on/off, just set the checkbox.style to graphical
to get the look of a command button.
It will stay depressed until the timer was disabled.

I continue to think that in this particular case
(timer run only 1 time) this was an action.
Delayed action, but an action.
