The +# natural time zone is in between the two: 8 hours ahead of GMT." +# +# From Paul Eggert (2001-05-04): +# This seems to be hopelessly confusing, so I asked Lee Hotz about it +# in person. He said that some Antarctic locations set their local +# time so that noon is the warmest part of the day, and that this +# changes during the year and does not necessarily correspond to mean +# solar noon.
