As I said earlier, I also feel the loss of the transition dates from LMT are an unwelcome loss to data in the database. On 2013-09-17 18:10, Stephen Colebourne wrote:
Thanks you very much for preparing this, I think it was vital on this occasion.

Changes affecting time stamps before 1970
Some zones have been turned into links, when they differ from existing zones only in older data that was likely invented or that differs only in LMT or transition from LMT. These changes affect only time stamps before 1943. The affected zones are: Africa/Juba, America/Anguilla, America/Aruba, America/Dominica, America/Grenada, America/Guadeloupe, America/Marigot, America/Montserrat, America/St_Barthelemy, America/St_Kitts, America/St_Lucia, America/St_Thomas, America/St_Vincent, America/Tortola, and Europe/Vaduz. From my perspective, these are the only changes that concern me. The change was IMO unecessary, deleted longstanding information and gained little if anything in return. The new values are, from the perspective of an end consumer, more confusing/worse/wrong than the originals (accepting that all the data is guesswork does not mean that one guess should take priority over another when that data has been in existence for a long time).
If others want to save the deleted data in these locations, then they need to speak up now. I don't intend on pursuing the matter further without indications that others understand the dubious nature of these changes.
