When declination and Latitude are changing appreciably perhaps the most general
method of estimating the time of local noon is:
1) Take altitude measurements of the sun when you can, hopefully between
sunrise and sunset.
2) The clock time of noon is that which gives a least mean squares fit of this
altitude/time data to the computed altitude at the DR position.
