    Re: Time Zone Designations

    Here's a question for those who have served in the Navy:  Are watches (the kind sailors stand, not the kind on your wrist) synchronized to local time?  In other words, if I cross a time zone boundary, does some watch get to go for either an additional hour or an hour less?

    This also reminds me about ZT vs UT -- according to the same "rules" that makes us take sites in ZT rather than UT, hourly DRs are also supposed to be plotted in ZT.  The first DR after crossing a time zone boundary is supposed to be annotated both in the previous ZT and the current one...




    Stan, do you suppose that this could contribute to a nautical equivalent to jet lag?
    I have always supposed that changing ship time as zone time varied was a way to make sure you were properly synched with the shore when you arrived.
