According to our sources last year, Turks & Caicos adopted Eastern time with US 
daylight-saving rules effective 2018-03-11 03:00. So, starting with tzdb 2017c 
America/Grand_Turk has been scheduled to fall back about 90 minutes from now, 
i.e., from Sun Nov  4 01:59:59 2018 -04 (EDT) to Sun Nov  4 01:00:00 2018 -05 
(EST) one second later. This agrees with an article in a newspaper last week 
cited below containing an advisory from the Turks & Caicos government. So as far 
as I can see, tzdb is should be OK for this transition. If you have information 
to the contrary please let us know the details so that we can fix tzdb.
