Does this mean that Turks and Caicos will NOT BE OBSERVING DayLight Savings time anymore?

Yes, starting in November according to 2014g. See its 'northamerica' file, which cites the following for why they won't change the clocks in November: http://tcweeklynews.com/daylight-savings-time-to-be-maintained-p5353-127.htm 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.
