but Edward Jaffe is correct; unless that offset is supplemented by a database of historical and current information about locale-specific daylight-saving/summer/official/... time in-effect intervals that would be hard to construct and difficult to maintain. There are indeed several such "databases" in existence; and, while they do have some limited usefulness for manual consultation, their coverage is too limited and their accuracy is too low to make them useful for reference from a conversion routine.
