    Re: resetting clocks on big ships
    From: Philip Ouvry

    In the Royal Navy clocks are normally reset at 1800 which is between the First
    and Second Dog Watches.   Each of the Dogs (only two hours long) are extended or
    reduced by 30 minutes.   For ships in company, the Senior Officer decides when
    clocks should be reset.
    
    When crossing the International Date Line it is usual to change the date at
    midnight.
