Currently the tz database has Dominica using AST (4 hours behind UTC)
all year.  This matches US Eastern Time right now, since the eastern
coast of the United States is observing daylight saving time now, and
Eastern Daylight Time is also 4 hours behind UTC.  So, if CNN shows US
Eastern time as matching your wall clocks today, that agrees with the
tz database.

If the tz database is right, things will change at 2:00 am on October
31.  At that point, your wall clock will agree with Atlantic Time in
North America (e.g., the time in Halifax, Nova Scotia).  If this isn't
correct please let us know.
