Given that the whole point of my message to which you are responding was
to describe in detail how this change doesn't affect our ability to record
accurate LMT transition dates for those zones, I'm not sure how to proceed
with this discussion.

So far as I can tell, nothing about this change makes it more difficult to
record an accurate LMT transition date for those zones.  The editing steps
required to record that information in the database files will be slightly
different.  That's all.

Apologies for just saying the same thing again in different words, but I'm
not quite sure what else to say.
