hello first background the Question is last i just spent an hour trying to edit America/New_York only to find US had been changed my two hosts disagreed by 1 hr and daylight savings time but not UTC prev US section used "max". apparently (i dont' have all tz revisions) someone change the last US rule this changes assumptions made in all rules of states using US in their Rules meaning one host assumes NY follows US from (19xx) forward, so does the other: but since US chaned they are an hour off -------------------------------------- Question: why was that a good idea ? and what if new Rules file becomes incompat with my libc and i cannot zic/compile and load "new localtime assumptions" ?? it seems rediculous however i'm guessing there is a good answer
