I, also, call generally call 'Time' whenever I turn away from the field to get reset, or dust, ...or whatever.
A trick that I generally keep in my pouch, and that I am very comfortable using, is the "Implied Time Out". That is to say, if, for some reason after action has ended, I 'fail to call time', and I have turned away from the field, then 'Time-Out' is
effected, implied and understood.
I don't have a problem selling it, ...or believing it.
