Turks and Caicos From Chris Dunn in https://bugs.debian.org/415007 (2007-03-15): In the Turks & Caicos Islands (America/Grand_Turk) the daylight saving dates for time changes have been adjusted to match the recent U.S. change of dates. From Brian Inglis (2007-04-28): http://www.turksandcaicos.tc/calendar/index.htm [2007-04-26] there is an entry for Nov 4 "Daylight Savings Time Ends 2007" and three rows before that there is an out of date entry for Oct: "Eastern Standard Times Begins 2007 Clocks are set back one hour at 2:00 a.m. local Daylight Saving Time" indicating that the normal ET rules are followed. From Paul Eggert (2014-08-19): The 2014-08-13 Cabinet meeting decided to stay on UT -04 year-round. See: http://tcweeklynews.com/daylight-savings-time-to-be-maintained-p5353-127.htm Model this as a switch from EST/EDT to AST ... From Chris Walton (2014-11-04): ... the TCI government appears to have delayed the switch to "permanent daylight saving time" by one year.... http://tcweeklynews.com/time-change-to-go-ahead-this-november-p5437-127.htm From the Turks & Caicos Cabinet (2017-07-20), heads-up from Steffen Thorsen: ... agreed to the reintroduction in TCI of Daylight Saving Time (DST) during the summer months and Standard Time, also known as Local Time, during the winter months with effect from April 2018 ... https://www.gov.uk/government/news/turks-and-caicos-post-cabinet-meeting-statement--3 From Paul Eggert (2017-08-26): The date of effect of the spring 2018 change appears to be March 11, which makes more sense.

Magnetic Media. 2017-08-25. http://magneticmediatv.com/2017/08/time-change-back-by-march-2018-for-tci/ From P Chan (2020-11-27): Standard Time Declaration Order 2015 (L.N. 15/2015) http://online.fliphtml5.com/fizd/czin/#p=2 Standard Time Declaration Order 2017 (L.N. 31/2017) http://online.fliphtml5.com/fizd/dmcu/#p=2 From Tim Parenti (2020-12-05): Although L.N. 31/2017 reads that it "shall come into operation at 2:00 a.m. on 11th March 2018", a precise interpretation here poses some problems. The order states that "the standard time to be observed throughout the Turks and Caicos Islands shall be the same time zone as the Eastern United States of America" and further clarifies "[f]or the avoidance of doubt" that it "applies to the Eastern Standard Time as well as any changes thereto for Daylight Saving Time." However, as clocks in Turks and Caicos approached 02:00 -04, and thus the declared implementation time, it was still 01:00 EST (-05), as DST in the Eastern US would not start until an hour later. Since it is unlikely that those on the islands switched their clocks twice in the span of an hour, we assume instead that the adoption of EDT actually took effect once clocks in the Eastern US had sprung forward, from 03:00 -04. This discrepancy only affects the time zone abbreviation and DST flag for the intervening hour, not wall clock times, as -04 was maintained throughout. Zone NAME STDOFF RULES FORMAT [UNTIL]
