    A question of time or times
    From: Alan S

    I thought I had found an error in the Nav and Jr Nav manuals used in Power Squadron courses, that being as follows.

    Respecting ZD's listed in Meridian Transit shots/reductions and other celestial body shots/reductions, the ZD's listed, dates were within the limits of Daylight Savings Time, Standard Times were used, without correction for DST to obtain UT.

    The above, I was told, applies to sights taken while "at sea", whereas respecting sights taking on land, say shooting from the beach, correction to ZD for DST should be made.

    Supposedly, this strange seeming, to me, situation arose from a dispute between the French and the British, some time, not sure as to how many years, back. I've looked through a couple of volumes of Bowditch that I have, without finding any reference to such discussions/arguments/agreements.

    While I will accept what I was told as correct, it coming from a competent instructor, could anyone here offer any clarification.

    Thanks in advance.
