Nobody don't know, there are 6 times difference in Canada.　that difference is 4.5 hour .
all so, summer time started march 10 to　Nｏｖｅｍｂｅｒ 2.
but Saskatchewan province has not do it. Ⅰ can understand　Ｃａｎａｄa is big country.
then that has 6 times difference .  Almost provinces are  going to enforce summer time,
but Saskatchewan don't do that, and some district don't do that.
Ｔhat matter make complicated society .
