665 Here, an incorrect reading would be there were two clock changes on 1973-04-29,
666 the first from 02:00 EST (\-05) to 01:00 CST (\-06),
667 and the second an hour later from 02:00 CST (\-06) to 03:00 CDT (\-05).
670 interprets this more sensibly as a single transition from 02:00 CST (\-05) to
671 02:00 CDT (\-05).
