BST starts at 1am on Sunday when all of us in the UK put our clocks forward by one hour. Since those short wearing, flip flop wearing Californian's aren't doing the same thing with Pacific Standard Time (who needs extra daytime when you get 12hrs in Winter) that means our reset time moves from 9am to 10am. So for you early morning guys that's one more hour to finish previous day/week bounties and less hour for the next. PS4 clock should set itself but it's probably worth checking.
