    Re: resetting clocks on big ships

    US Navy standard - Quartermaster QM Ratings are responsible for this (at
    least on my boat). Everyday at 0800 there would be a time check. We ran on
    Zulu for all OPS and standard ship time was the local time zone. The QM's
    would confirm ship time in the more important spaces....Engine Room, CIC,
    Skippers clock, wardroom and Bridge. GPS time sinc is used more now than in
    the past......

    On large vessels  you usually have a three watch system the hour of
    advance or retard
    is divided between the watches. Twenty minutes on the evening 8 to 12,
    twenty on the middle
    and twenty on the morning watch. The change takes place on the boundary of
    the zone e.g
    7.5 West or thereabouts. I experienced a Captain who wanted to keep
    apparent time at ship,
    this meant rushing to the clocks to advance or retard as soon as the sun
    at Merid.Alt dipped.
