Boston is always GMT-4 or -5, and there are only two
dates when the variable comes into play.

Of course planes depart London on local time, not Zulu.

The U.S. & Britain don't change summer/winter times necessarily on the
same date. (I think the gap is most noticable in autumn.)

(Or perhaps that's what you were saying? But as I recall, the autumn
gap is a couple of weeks.)

Nit - UK springs ahead a week before US. They fall back on the same date.
