It never affects me. My sleep patterns are so erratic anyway that I could move my clock back and forth every day and never notice.

My biggest complaint is that I have to have one of my boys change my wall clock for me because it's too heavy for me to lift off the wall and put back. And they were both over here today and what did I forget to ask one of them to do? Yep......so that clock will remain an hour slow until one of them comes back over!
