LOW), via (HIGH LOW), to (HIGH LOW MICRO)? Yes. Both (HIGH LOW) and (HIGH LOW MICRO) are valid now. It is useful to accept (HIGH . LOW) as well. Shall I fix time-less-p and time-subtract to deal with (HIGH LOW MICRO) arguments as well? Yes, please do. Should they deal with (HIGH . LOW) too? It would not be a bad thing. What about the return value of time-subtract (and time-add): should it be backward compatible in the sense that it returns (HIGH LOW) if both its arguments are of that format? Yes.
