It actually sets "standard time" to what is currently daylight saving time, and deletes DST.

> It actually sets "standard time" to what is currently daylight saving time, and deletes DST. As the current maintainer of the timezone database observed: A *lot* of computer software assumes that timezone abbreviations like "PST" have their longstanding meanings. This software was obviously misguided, but it's out there and changing it will be quite a hassle. I don't envy people who will have the responsibility for cleaning up the resulting mess where "PST" has one meaning for older timestamps and a different meaning for newer ones and existing standards like Internet RFC 5322 continue to say things like "PST is semantically equivalent to -0800". * https://mm.icann.org/pipermail/tz/2022-March/031239.html https://mm.icann.org/pipermail/tz/2022-March/031239.html

  Similarly, people thought the world would burn in flames due to Y2K, when dates were going to overflow their bits, kill everyone, and lose banking information. As things happened, the date passed with nary a blip for me or anyone I knew. I suspect this will be similar.

    Y2K required hundreds of billions of dollars worth of effort to keep it from being a disaster, and it still actually resulted in some significant issues: "In Sheffield, United Kingdom, a Y2K bug caused miscalculation of the mothers' age and sent incorrect risk assessments for Down syndrome to 154 pregnant women. As a direct result two abortions were carried out, and four babies with Down syndrome were also born to mothers who had been told they were in the low-risk group." https://en.m.wikipedia.org/wiki/Year_2000_problem https://en.m.wikipedia.org/wiki/Year_2000_problem

      Nobody notices when things go right. :)

  I find it hard to imagine that systems which store "PST" and rely on a hard-coded assumption that it is -0800 would be robust to normal changes in time zone rules, which already happen regularly. Like surely those systems would have already broken in 2007 when the rules of America/Los_Angeles changed such that the date of the yearly transition between PST and PDT changed.

Wow. Lawmakers continue to amaze me with their stupidity.
