Time Change! Remember Fall Backwards!
Remember, at 2am tomorrow morning it will be time to change your time pieces. Of course, it is permissible to set them before you go to bed. You do not, I repeat, do not, have to wait until 2am to change the time.
When I was a time keeper at the Atlanta Post Office, always we could count on at least some people coming in hour late or early because they did not set their clocks or setting their time pieces opposite and coming in 2 hours late. One person even came in 4 hours late. He ended up being a supervisor then the divisional operations manager.
