If you mean - what time will the cruise ship clocks reflect; I have been told that the ship's clock will be the time reflected from the port you ship out of and will remain as such. The ship will tell you the time that the particular port is at upon arrival. At least, this is what I was recently told.
Peter1 is correct-the ship's clock does not change. Departures and arrivals are always ship's time, which is the same as the ship's port of departure.
Have a great time-you'll love cruising!!
we were on the enchantment about 3 weeks ago. the time on the ship does change when we went to cozumel and belize. we had to turn the clocks back an hour the night before.
like i said in the above post, the time will be differant than fl. time.the night before you arrive in cozumel you should turn the clocks back an hour. do this when you go to bed .
have a great cruise and if you go to belize do an excursion because the port area is not much to speak of.
