CelNav's explanation only uses the example time and date of January 22, 2017 GMT 17:20:14. It's easy enough to figure out any other date and time.
If the time had been 17:38:14 then the figures would be as follows (not showing "b");
c= 17:30= 77° 30'
d= 2° 04'
Total= 79° 34'

Carlos, you may have missed a finer point... The original instructions clearly state you use the closest whole hour to find OT... So it would follow that if GMT is 17:38:00 one would use 18 hours + or - A table - not 17 (The Table 4 instructions use a similar example). There may then be some difference in finding E if the OT date changes or to the B correction as per the Table example.
