    I think I liked this article as it was the one that caused the little bulb
    over my head to light up.  I had read a half dozen articles on the date
    line, from grade school level up, complete with colorful diagrams, but never
    really grasped the concept. Just plug and chug based on a set of rules.
    
    My problem, as usual, frame of reference. I kept thinking of it in 20th
    century terms, calendar and watch.  With this article, the frame of
    reference shifted to Sun time.  Bingo, unification theory for the terminally
    slow.  I hop on an aircraft at LAN, head west and circle the globe at 15d
    per hour, and I arrive back at LAN.  Sun time, no time passed.  Digital
    watch shows the same time as when I left, but a day later despite the fact
    it had been LAN for me the whole flight.   Going west, I would see two "Sun
    days," but only one would pass on my watch.
    
    Now I don't need to remember any rules, I understand the concept.
