What Time Is It, Again?

"There are many challenges a crew faces when they deploy. Today’s challenge is changing time zones. As we travel west, we'll have to set our clocks back nine or ten times, depending upon where we finally end up. Then of course, the opposite will be true as we return. Even operating in the same fleet area can require time changes every few days or weeks.

One tricky bit is planning when to execute a time change. Since the ship operates around the clock, no matter when you schedule a time change, it's going to be a source of consternation to someone. If you move clocks back during the day, some will complain about the extra hour of work. If you move them back at night, others will complain about the extra hour of watch during what can be a long, slow night.

Another tricky bit is communicating to the crew when the change will happen. Every path of communication must be used. The Plan of the Day must include a schedule item. Word must be passed and reiterated through the chain of command at morning quarters and the evening operations brief, and announcements must be made over the 1MC. Still it seems there’s always somebody who doesn’t “get the word”."

You would think that on a ship at sea the schedule would all run on ship time, sort of like the do in space..Just a suggestion
