    A one second error equates to about a quarter of a mile. In the middle of the ocean where celestial navigation is really meant to be used that is trivial. 

    If I am close in making landfall hopefully I can see. If I can’t see celestial navigation isn’t gonna help me anyway. I’m generally really happy with a sight that agrees with GPS + or - a mile.

    This is all my way of saying I’m not very worried about UT1 versus UTC versus Zulu time or what ever new alphabet soup arises.  I’m not trying to synchronize the power grid. I’m trying to get my boat to go generally the right direction for long enough to make a Landfall.

    One can choose the time server used by his cellphone.  I use a time server that gives UT1 times.  I then sync my wristwatch to my cellphone, and use the watch for sextant sights.

    As far as I'm concerned, they could just continue indefinitely publishing the Nautical Almanac with UT1 times.
