Avoid underflow on arithmetic with possibly-first transition times
A transition time may represent the beginning of time; as such,
arithmetic on it might underflow, e.g. on adding a negative zone
offset to compare with a given time. So move the arithmetic to the
other side of the comparison in such cases.
