As long as we're considering decreasing the historical fidelity of assorted pre-1970 timestamps, I'd like to make a modest suggestion: forget all the "LMT" offsets for years before standardized timezones prevailed, and just assume that the oldest documented standard-time offset in each zone goes back indefinitely far.
I would support this, provided we keep the LMT offsets in backzone so that (more or less) casual users wouldn't notice the difference.
I would actually say that, if we're going to do something like that, there should be a way to put a "not valid before" marker into the zone data and have the functions return either an error or a clearly nonsense answer. -- Clive D.W.
