Yes, starting in November according to 2014g.  See its 'northamerica' 
file, which cites the following for why they won't change the clocks in 


2014g models this as a change from Eastern Daylight Time (EDT, UTC-4) to 
Atlantic Standard Time (AST, UTC-4) on November 2.  That is, the clocks 
won't change in November, but the alphabetic time zone abbreviation 
will.  Admittedly this disagrees with the headline of that news article 
(which implies they will use DST year-round), but the longstanding 
convention of the tz database is to model "perpetual DST" as standard 
time. and since the time stamps will be correct nobody will much care 
about the distinction.

> What will the time zone name be for the Turks and Caicos....currently I have America/Grand Turk? Will this change?

No.  All you should need is an updated (2014g or later) database.
