A related issue that came to my attention a couple of years ago is that
of America/St_Johns, which until 2011 had a DST transition one minute
_after_ midnight, resulting in non-contiguous days on the backward
transition. (There are a few other historical examples of such zones.)

At least Chile (America/Santiago) and, last I looked, some other South
American timezones still have transitions at exactly midnight.
