Hawaìi and Aridzona have it right.
What a great idea --- let's all agree to start lying to ourselves about as simple a thing as "what time it is". What could possibly go wrong. Colossal failure to think. Small wonder lying is part of the culture.
I believe our colonies, like Guam, Puerto Rico and the Virgins, also don't use Fake Time. Elsewhere on the continent Yukon, most of Saskatchewan, some locations in Québec east of 63° west longitude (e.g. Blanc-Sablon), Southampton Island, and some areas in British Columbia stay on standard time all year.
Prolly won't happen this year but I seem to recall it being so cold that I needed to run a wood stove, during Daylight Savings and Loan Fake Time.
