I did a ~13 day eastbound TPAC in March that had a 9 hour change (UTC+8 to UTC-7). Time change was done every day at 1600, and dinner was at 1800, so it was like eating at 1700 every day of the time changes, which was front-loaded so most of the time changes came in the first week. All for the convenience of the crew.

I find it much easier on a ship with daily hourly changes than being dumped on Europe after a TATL with your arrival at midnight at your place of departure. If there was a fast sea voyage from the west coast U.S. to western Europe, I'd do it.
