I have no special needs for the value of that constant. It should just
be a valid time value in the scope of Emacs 27, and all timer functions
should accept it and return plausible values. A NaN would be OK, if
accepted everywhere.
For older Emacsen, I will use my own compat version of that constant
anyway. Either '(0 0) as it is the case for the last 15 years, or '(0 -1).
Best regards, Michael.
