    Problem solved.

    I am at long 175E  not 180E. The earth rotates at 15° and hour. The time difference  60 * 15 / 5   = 20 minutes.  The error in my calculation was 23 minutes.

    Phew! That is a relief. I may pass my Board of Trade exam after all. The sun is out and the sun's max altitude has dropped below 60° so I may relax and take a noon sight. I should  do an equal altitudes for long but that is too much like hard work.  A long by chron in the afternoon will be easier.
