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).
I always considered "is DST in effect, and if so, what is the offset from standard time" to be an important question, even if the abbreviation is not important. But I agree that it doesn't seem to have mattered to the people in Creston at the time, so it's probably fine if the tz database doesn't worry about it. --apb (Alan Barrett)
