Hmm.  I think the way that the code in pgtz.c is set up, it just assumes
that either "Eastern Standard Time" or "Eastern Daylight Time" should
map to our US/Eastern timezone (which is a DST-aware zone).  Running
your system in non-DST-aware mode is what's confusing it --- the offset
to GMT is an hour different than it "should be" at this time of year.

Should pgtz.c try to detect this situation and handle it by mapping to a
non-DST-aware internal timezone?
