Hence, true Clock time = Observed Solar Time + Total correction

where, Total correction = +12h + Longitude correction + mid-eclipse equation of time

and, Observed Universal Time = Clock time - time zone

For example: for 1842 Jan 26 at Eutin solar time of 1C was 4h 44m = 15h 52m 08s (UT), the predicted time was 15h 13m 53s (UT) which is a large 38m 15.7s difference, and

for 1842 Jan 26 at Eutin solar time of 4C was 7h 38m = 18h 46m 08.7s (UT), the predicted time was 17h 43m 46s (UT) which is over 1h difference ?
