The testing points up that the "northamerica" file specifies that Phoenix did a couple of 1944 changes at one MINUTE (rather than one HOUR) past midnight; if anyone has leads on the correctness of this, I'd love it. The three 00:01 Arizona transitions in 1944 are taken from Shanks's American Atlas, page 19, table AZ#1. My guess is that they are not just a typo, and that 00:01 was an 1940s Arizona tradition. Shanks's table AZ#2 also shows a transition at 00:01 for the western part of the state (e.g. Kingman), which switched from Pacific to Mountain time in 1945-03-07; this transition doesn't appear in the tz tables because it's before the 1970 cutoff. By the way, Shanks makes a rare comment before the Arizona tables as to how wild and woolly Arizona's clocks were. WW II wartime ended early in Arizona; he doesn't say way. He doesn't know when Yuma County shifted to Mountain time. My guess is that there was serious disagreement early this century, even among Arizonans living in the same place at that time, whether Pacific or Mountain time was being observed. I'd also guess that Arizonans stay at MST all year nowadays partly because they have a dim institutional memory of tempers flaring when people mess with the clocks. 3. Also, the testing points up that Budapest was supposed to have switched from using standard M-Eur rules to using its own rules on July 1, 1918, but that the new rules didn't specify use of DST until 1919. Again, if anyone knows whether Budapest turned off DST early in 1918, I'd appreciate a pointer. That was a typo in my transcription of Shanks for Hungary in 1918. Sorry.
