My husband and I were on an Atlantic crossing cruise about five years ago and we got the usual brochure in our cabin about the next day's events. There was a notice that instead of having us change our clocks an hour several times during the crossing that the Captain had decided to do it all at once the next night. This was to make it more convenient for the passengers. Thus the notice said that there would be no entertainment, dinner hours would end at 7 and we could retire early to adjust to the change in time. We were astounded as it sounded so strange. We went to bed and saw our cabin attendant the next morning and mentioned how strange the time change plans sounded and this had never happened to us before. She grinned and asked us what day it was!!!! We fell for it hook, line, and sinker.
