Then I wish you had said exactly that, instead of having me go off on a tangent. Maybe I am misinterpreting something, but I don't understand why you are being confrontational about this. I am presenting results from 2 different TZ parsers, using algorithms developed independently. I thought this would be interesting and relevant to this topic. I don't understand the point that you are trying to make.

    No. In my mail, I tried to say that your assertion

     >>   the fact that "2:00" is Wall-time, not S-time or U-time:

    is irrelevant for the issue because Kaliningrad has an "S-time"
    when two transitions are coalesced.
