I imagine this will happen if Massachusetts goes through with the change to year round Atlantic Time, but otherwise the name of the zone Boston is in is America/New_York. I believe the zone naming is explained in the theory file. Long story short: tzdb is not a mapping between cities and their time zone, it's a list of time zones which happen to use city names as keys.

Boston is unfortunately not listed in the Time Zone Database. Are you going to add it?
