    Re: Time Zone Designations

    I lost track of the number of times I crossed the Pacific and Indian
    Oceans while in the USN in the 80s and 90s.  The ship(s) always kept
    zone time in order to provide a normal work schedule (meals, sleep,
    work, flight ops, etc) for the officers and crew.  As to the watches,
    depending on "where in the world" the ship was located depended on how
    many watch sections were "formed" by the Senior Watch Officer.  Underway
    in the Pacific, we typically had 3 watch sections formed, but in a
    designated combat zone we usually went to 2 sections known as "port and
    starboard".   The Commanding Officer (CO) did have some discretion as to
    the number of watch sections to be formed up.  The ships navigator made
    a recommendation to the CO as to the day to move ships clocks forward or
    back.   As I recall, we always moved ships clock one hour at "midnight".
      While this sounds like one section was getting the brunt of the "clock
    changes" in reality the ship was in 3 sections most of the time during
    the "cruise" so the midwatch was never the same section, unless we were
    in 2 sections.
    As mentioned earlier the ship always served "midrats" which was the 4th
    meal of the day.
