What about time at JAGS McCartney International Airport GDT/MBGT on Grand Turk?

T&C rules were updated in tzdata 2017c with info from July and August:

+# 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

+# From Paul Eggert (2017-08-26):
+# The date of effect of the spring 2018 change appears to be March 11,

It would help diagnose issues if you could provide distro or package version
info and time change diagnostics like:

$ apt list tzdata tzcode
tzcode 2018e-1 x86_64 [installed, manual]
tzdata 2018e-1 x86_64 [installed, automatic]
$ zdump --version
zdump (tzcode) 2018e
$ zdump -Vc`date +%Y`,`date -d'next year' +%Y` America/Grand_Turk
