Oh great! time to run around the house setting all the manual wind chime and strike clocks ahead an hour. Not so bad.
However, it's a pain in the fall! Either have to set them all ahead 11 hours which involves moving the hands forward and waiting for the chime and/or strike to finish then move forward another 1/4, 1/2 or hour, or just stop them all for 1 hour. Of course with that plan, I realize hours later that I forgot to start them again, and have to do the move forward anyway!
