I hope the Sunshine Protection bill fails not only because it's problematic for TzDb but also because it creates the "kids in the dark morning" problem which is was the reason the 1973/1974 "DST experiment" was reversed. Seems to me like that could happen again.

The 1974/1975 D.O.T. studies are available online to read (linked in one of my prior emails). Yes,  a few children were killed in the morning during the early months of the experiment (which as I noted began on one of the darkest days of the year creating the largest jump scare effect of a later sunrise). The deaths were offset by less children killed in the afternoon due to the later sunsets. The final version of the D.O.T. study relied heavy on public opinion of people who never were given the chance to experience losing morning sunrise time gradually over three months (lastSunOct-lastSunFeb).

If H.R. 139 becomes law and is made effective prior to November 1st or delayed until next year (no effect seen until November 7th 2027) the country will have the opportunity to experience a gradual loss of morning sunrise time (no jump scare). The last change (made effective 2007) included the right to revert. Not currently in this bill (or S. 29).

(You can hold out hope for H.R. 9638, which has no senate version and would have to make it through a committee that already approved H.R. 139 and a house that overwhelmingly approved H.R. 139. I would not expect it to progress.)

Now, back to the work of testing systems and getting them ready for the potential change as written in H.R 139.
