Turks & Caicos switched to U.S. DST dates?

On 2007-03-15 Chris Dunn reported to the Debian bug list that the
Turks & Caicos Islands (America/Grand_Turk) changed their DST
transition dates this year to match the U.S. dates; see Debian bug
415007 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=415007>.  He
made no mention of the time, so I guess we should continue to assume
transitions at 00:00 local time.  It'd be nice if someone could
confirm this with a more-authoritative source.
