I will try and find a general rule for this, but it may take awhile.

# We go with the Almanak, except for two claims from Shanks: # 1. In 1968 standard time wasn't switched to GMT until Oct 27; # this affects only the time zone name and dst flag.

I wonder if this one is such a good idea. Here is the actual quote from the almanak (paraphrased): In the year 1968 "summer time" was finally made standard time in Iceland by law number 6 from April 5th that year. The change was made on April 7th at 2:00 GMT and the clock was adjusted forwards by one hour. Clock time in Iceland has since then been on GMT the whole year round. Of course, both Shanks and the Almanak have the same actual time offset for summer 1968, but technically it is the Almanak that is correct. Shanks chooses October 27th as the transition time because that is when the end of the summer time would otherwise have been (by the previous general rule). -- Adam David <adam@veda.is>
