This article mentions that Cuba tried permanent summer time in 2004-06. This makes me wonder, has anyone ever tried permanent summer time and not given up? I know Russia attempted in 2011-2013[1] (before switching to permanent standard time), and the US did it in 1974[2] before going back. I know British Columbia did it this year, but I wonder how long that will last. BC is pretty North, and I wonder how local Canadians will feel about the very dark mornings in winter.

Edit: Updated comment to say "permanent summer time", since "permanent DST" is rather incompatible a statement.
