we now have a situation in which the transition from DST off to DST on results in an ambiguous local time period for Ireland. For what it's worth, this particular situation is not new in tzdata. For example, Europe/Kiev has a transition from +03 (without DST) to +02 (with DST) on 1941-09-19 at 24:00, which means that timestamps that day between 23:00 and 24:00 are ambiguous in Kiev. This transition has been present since the release of tzdata 1999j two decades ago. I'm sure there are other examples.
Every time zone that has seasonal offset changes has periods per year where local time does not exist (spring forward) and ambiguous duplicated local time periods (fall back). Or am I missing something different? -- Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada This email may be disturbing to some readers as it contains too much technical detail.
