A large number of articles bubbled up in my inbox (and RSS feeds) this morning. Some were just open tabs from the weekend. From the Post:

And now, to work, perchance to write...
The day after a 3-day, 3-flight weekend doesn't usually make it into the top-10 productive days of my life. Like today for instance.
So here are some things I'm too lazy to write more about today:
Now, to write tomorrow's A-to-Z entry...
The European Union Parliament today voted 410-192 to allow member states to end Daylight Saving Time in 2021:
The vote is not the last word on the issue but will form the basis of discussions with EU countries to produce a final law.
The countries have yet to take a stance.
A parliament report in favour of operating on a single time throughout the year said scientific studies link time changes to diseases of the cardiovascular or immune systems because they interrupt biological cycles, and that there were no longer any energy savings.
What this actually means requires one more EU-wide step:
All 28 member states would need to inform the European Commission of their choice ahead of the proposed switch, by April 2020. They would then coordinate with the bloc's executive so that their decisions do not disrupt the functioning of the single market.
Last year, the European Commission proposed abolishing the seasonal clock change after an EU-wide online poll showed overwhelming support. It has been accused, however, of rushing through the vote ahead of European Parliament elections in May.
Countries that wanted to be permanently on summertime would adjust their clocks for the final time on the last Sunday in March 2021. Those that opt for permanent wintertime would change their clocks for the final time on the last Sunday of October 2021.
The British government has yet to offer any formal opinion on the proposal, which risks creating fresh problems over the status of Northern Ireland after Brexit.
I think we can predict, just by looking at longitude, which countries will go which direction. The UK has made noises that it will keep the twice-yearly time changes, thank you very much. My guess is that Portugal, Spain, the Baltics, and other countries at the western ends of their time zones will opt for standard time, while other countries will go to summer time. That would prevent the problems I outlined when this measure first came into the news a few weeks ago.
The EU could vote this month to end Daylight Saving Time in 2021, but it turns out popular support for the measure may have been...überwiegend Deutsch:
Time is up for European Union-mandated daylight savings time. The European Commission and European Parliament have agreed on that. All the relevant committees in Parliament are for the change, according to Germany's conservative Christian Democrat (CDU) MEP Peter Liese, who has devoted a lot of time to the issue.
Now that the lead committee on transport and tourism has given its blessing, by a large majority, EU lawmakers could vote on the change by the end of March. After that, all 28 member states will need to rubberstamp the ruling.
European Commission President Jean-Claude Juncker's brash statement back in September, asserting that the amendment would go ahead quickly, has proven to be premature. At the time, Juncker was referring to an overwhelming response to an EU online survey, where an unexpected 80 percent of respondents said the practice of changing the clock twice a year was outdated.
But the survey was not representative, with 3 million of the 4.6 million votes coming from Germany. This led to diplomats from smaller EU countries complaining behind closed doors that the European Commission wanted to impose German will on the other states through sheer populism.
That's great, but some member states want to keep daylight saving time. Won't that be fun.
Oh, I love these stories. On today's Daily WTF, editor Remy Porter describes the world I grew up in, where dates were dates and 30 December 1899 ruled them all:
If you wanted to set a landmark, you could pick any date, but a nice round number seems reasonable. Let's say, for example, January 1st, 1900. From there, it's easy to just add and subtract numbers of days to produce new dates. Oh, but you do have to think about leap years. Leap years are more complicated- a year is a leap year if it's divisible by four, but not if it's divisible by 100, unless it's also divisible by 400. That's a lot of math to do if you're trying to fit a thousand rows in a spreadsheet on a computer with less horsepower than your average 2019 thermostat.
So you cheat. Checking if a number is divisible by four doesn't require a modulus operation—you can check that with a bitmask, which is super fast. Unfortunately, it means your code is wrong, because you think 1900 is a leap year. Now all your dates after February 28th are off-by-one. Then again, you're the one counting. Speaking of being the one counting, while arrays might start at zero, normal humans start counting at one, so January 1st should be 1, which makes December 31st, 1899 your "zero" date.
Our macro language is off-by-one for the first few months of 1900, but that discrepancy is acceptable, and no one at Microsoft, including Bill Gates who signed off on it, cares.
The Basic-derived macro language is successful enough inside of Excel that it grows up to be Visual Basic. It is "the" Microsoft language, and when they start extending it with features like COM for handling library linking and cross-process communication, it lays the model. Which means when they're figuring out how to do dates in COM… they use the Visual Basic date model. And COM was the whole banana, as far as Windows was concerned- everything on Windows touched COM or its successors in some fashion. It wasn't until .NET that the rule of December 30th, 1899 was finally broken, but it still crops up in Office products and SQL Server from time to time.
The .NET epoch began 1 January 2000. Except for DateTimeOffset values, whose epoch began on the non-existent date 1 January 0. Or DateTime values (now deprecated) which start at the beginning of the Gregorian calendar in 1753. (Same with SQL Server datetime types.)
The bottom line: dates are hard.
The island-nation of Kiritimati just became the first place in the world to enter 2019. Good on 'em.
People may have noticed the Daily Parker tradition of welcoming Kiritimati into the new year. On 30 December 1994, Kiritimati changed time zones from UTC-10 (Hawai'i time) to UTC+14 (ludicrous time), in part so they could become the first place in the world to start the 21st Century. Technically, it worked.
However, since the highest point on the small island (population 6,500) rises only 13 m above the Pacific, the country is completely vulnerable to climate-change-induced sea-level rise. It probably will not be the first place in the world to greet the 22nd century.
So, happy new year, Kiritimati! I hope you outlive me.
We just got back from the vet. The x-rays show that Parker's leg is almost completely healed, so he's finally cleared to go back to his play group. He has no idea about this right now but tomorrow morning he'll be very, very happy.
Now I'm about to run to my office, so I'm queuing up these articles to read later:
OK. Chugging some tea, and hitting the CTA. More later.
Saturday and Sunday, the Apollo Chorus sang Verdi's "Requiem" three times in its entirety (one dress rehearsal, two performances), not including going back over specific passages before Sunday's performance to clean up some bits. So I'm a little tired.
Here are some of the things I haven't had time to read yet:
Other stuff is going on, which I'll report when I have confirmation.
All the news yesterday and today has talked about Mike Wolff's new book, and how it puts into black-and-white terms what we already knew about the President. I'm reading a lot of it, and I've even pre-ordered David Frum's new book, coming out a week from Tuesday.
Fortunately, Chicago magazine published an article today about the origin of time zones in the United States, which is political but only in the nuts-and-bolts sense and not really in a partisan way. And Chicago has the story because, basically, Chicago invented time zones:
America was divided into its (mostly accepted) time zones in Chicago. Which makes sense. Chicago was and still is the biggest railroad town in the country, and the railroads were, in both the United States and Europe, the catalyst for the creation of time zones. In fact, there’s a historical argument that the challenges of scheduling trains inspired Albert Einstein’s development of the general theory of relativity...
Take this time and distance indicator from 1862: when it was noon in Philadelphia, it was 12:04 in New York, 12:06 in Albany, 12:16 in Boston, and 11:54 in Baltimore. Meanwhile, it was 11:10 in Chicago, 10:59 in St. Louis, and 11:18 in Indianapolis. Synchronizing relative time across cities might have inspired Einstein’s thought experiments, but it was a poor way to run a railroad.
In 1880 Britain officially adopted Greenwich Mean Time. The Canadian railway engineer Sandford Fleming and the astronomer and meteorologist Cleveland Abbe, chief scientist of the U.S. Army Signal Corps, began correspondence about a worldwide system of time zones, proving themselves persistent advocates of what Fleming called terrestrial time. Their work was presented at the Third International Geographical Congress in Venice in 1881, the General Conference of the European Geodetic Association in 1883, and the American Association for the Advancement of Science in 1881 and 1882.
Such a system was politically messy, requiring the coordination of governments for which time zones had political symbolism. But the railroads had only the bottom line to consider.
And so, the standard time zone was born. And at this writing, according to the Time Zone Database (of which I am a contributor), there are only 494 of them.
Just a minute or two ago, Kiritimati (Christmas) Island became the first place in the world to enter 2018. This happens every year—or, at least, every year since Kiritmati moved from UTC-10 (the same clock time as Hawai'i) to UTC+14 (the same clock time as Hawai'i but a day ahead) so they could be the first place on earth to enter the 2000s.
So, just a few minutes ago, that choice caused a fascinating consequence.
As of right now, and until the next person is born on the island (which could be days or weeks because of its small population of 6,500), every single adult on the island will have been born in the 1900s, and every single child will have been born in the 2000s.
As each successive time zone moves into 2018 today, this will continue to be true until the first baby is born before 1am in a particular zone. My guess would be that New Zealand will probably have a baby born before 1am, and eastern Australia certainly will, which means the 1900s/2000s split will only last 3 or 4 hours.
It's just an interesting consequence of a public-relations decision a tiny Pacific atoll made 18 years ago.
