If anyone is confused about the US/Pacific-New that appears in the list, apparently it has something to do with a bill that was that was passed by the House in 1989, but never signed into law. It has to do with delaying the switchover until after the election. Read more about it at http://catless.ncl.ac.uk/Risks/13.87.html and it should be the first posting. Or just do a search for US/Pacific-New.
