Since I have zero regard for tz abbreviations in any case (aside from the need to retain the API), I personally think that doesn't matter in the slightest (and nor do I gather it ever mattered to the people concerned). It appears as if they considered themselves to be PDT during a period of WWII when daylight savings was mandated - by simply declaring they were in the pacific timezone (+1) they managed to avoid voilating the letter of the law, without doing anything at all... I could add the transitions to give effect to that if anyone really feels it is important. I can certainly add some comments noting the issue. kre
