Thanks for catching that; I had missed systemv somehow. However,
Indiana will observe DST next year, so we probably should stop
equating Indianapolis with "no DST". Also, in reviewing the comments,
they need updating in the light of the current US plans for DST, and I
found the first line a bit confusing.
How about the following further patch? It attempts to address these issues.
Does anyone know when the SystemV rules were written? If so, that
"1976" below should be changed to that date. It had to be some time
in the 1976/1987 time frame.
