    In the US Navy, ships maintain local time. Deck logs and all other
    navigation logs are kept in local time. Any communications leaving the
    ship use GMT.

    Interesting. My understanding (which may be faulty) is that the Royal
    Navy's practice, through the two World Wars, was to maintain ship's time
    on GMT, at least throughout the Atlantic and Mediterranean. (They may
    have done something different in the Pacific theatre.) I can understand
    that other navies would prefer to use zone time. However, in an era of
    long-distance radio communication, wasn't it difficult if each ship used
    its own time based on its LAN?
    Navigation must use GMT, of course. Presumably logs of radio
    communications use that or some other zone time (perhaps that of the
    Admiral's headquarters). Orders from ship to ship could be similarly
    timed. Still, it sounds a bit awkward to have everyone's wrist watches
    set to a ship's time which differs from the time being used between
    ships. (Naturally, such considerations did not apply to merchant ships
    individually plying their trades in the era before general radio
