Could people stop appropriating rap culture in their tech blogs (etc.) with patronizing garbage like "While I was initially building this talk, I found myself listening to the words of my absolute favorite modern-day philosopher: Nas"?

People probably are encountering some level of philosophical questions in the art they're engaging with. If that's in Nas or elsewhere in rap culture / hip hop / whatevs, why shouldn't someone be talking about it or riffing off it?

Sorry you found it patronizing, I guess. Nas does great shit, though.

I did, because you followed with "I’m not really sure what to take from all this, other than if Nas is really concerned about computer science and how it relates to time, then dammit, we should be concerned, too." The theme of the song you're talking about is lukewarm neoludditism. Not vague concern for computer science. And you're still doing it, infantilizing his music. He doesn't do "great shit," you could say he…

Ah, totally see where you're going with this. Definitely my bad- I really should have ended this time programming post with a long treatise on hip hop styles and lyricism rather than toss in an obvious joke as a small aside to the longer point.

(I am being patronizing here, fwiw.)

Slightly off topic but I wonder how you handle time where dilation is present. For example if a spacecraft travels to mars and there is mars local time, plus time dilation from the journey, when does a transmission start from a reference frame? Not UTC related for sure! Or is it? And then what happens if someone else goes there in a different orbital pattern and the dilation is different. and then there is the questi…

This just in: people of all races and creeds and lifestyles enjoy listening to good music. If Nas didn't want certain people listening to his music, he wouldn't sell it at WalMart.

> This stuff moves a lot, too: the tz database (also known as the Olson database), which is the listing of timezone rules we use as programmers to calm this chaos, gets updated many times a year.

Without looking it up, I would say the last change happened when North Korea decided to sync its timezone with South Korea... or have they reverted that since Trump cancelled their summit?

Sadly I didn't have enough time to read the whole article...

But I wish we could all just use one time. For some, midday would be 12, and for others it might be 19, but we already all use the same dates regardless of whether February is winter for one location or summer for another.

You think time has some weird edge cases, but then you get into a discussion about cultural appropriation and you realize how lucky you are to only be worrying about calendars.

With care you can calculate UTC independent of any time dilation. Local system is mostly irrelevant in terms of UTC and we already deal with systems with different clocks due to leap seconds.

Now you might care about communication lag, but nothing makes earth unique so you need to handle lag with arbitrary endpoints anyway.

Having dealt with that crap… that should be an interesting read

> Recurring events

Whelp, shit just got very very real, and I actually disagree with Zach here:

> If someone held a gun to your head and demanded in the next week you either 1) programmed a comprehensive system that included full support for recurring events, or 2) invent full-scale ready-to-go-to-market cold fusion, then you should abolutely start brushing up on atomic physics.

You should just beat yourself with the gun (or whatever the nearest heavy implement is) immediately, no cause to prolong the pain, you're not Harold.

Congratulation you jokester, you're the second paragraph of the "Timezones" section.
