I honestly don't think about it. I get up more than an hour before work, and I go to bed early enough to not need an alarm. I only have 4 clocks that don't change automatically (wall clock, oven, two cars), and I just go by the time on my phone, so I just change those when I notice they're wrong.

That said, I think the whole thing is stupid. It throws my sleep off for no reason (less/more time in the morning when it changes), so why keep it?
