'Falsehoods programmers believe about time: - Every day has a sunrise and a sunset'

Right? I am reliably put into this weird emotional state of being simultaneously entertained and chagrined at the propensity for technologists (and I very much include myself in this criticism) to make these kinds of assumptions, and the edge-case bugs that fall out of them.

And it's a reminder that "edge case" is relative. It's not an edge case for people who live there!

reminds of the Computerphile Tom Scott video "The Problem with Time & Timezones" https://www.youtube.com/watch?v=-5wpm-gesOY and why I will never implement datetime myself

Nobody ever got fired for using the provided datetime.

Falsehood #2: Every day starts at 12:00 am midnight.

Wot, what's the false case?

Some cultures end the day at (wait for it...) sunset.

And now we're back to the original problem.

I hear you. It almost always is what people meant but most of us (myself included) rarely think about the distinction.

I've just gotten to saying ET (or equivalent) all year-round .

That’s the battle I fight: persuading people that saying “Eastern” is accurate and sufficiently precise. Precise and inaccurate is a bad combination.

I sometimes wonder how many bugs are lurking in systems using GPS for navigation at 180th meridian (where longitude goes from 180 to -180).

IIRC there was a bug in an early version of a certain fighter jet where it would go inverted when crossing the equator. Oops.

That becomes fairly obvious when you consider Arizona doesn't observe DST, but Utah is the same longitude (lies directly north) and does observe DST.

Yep. And there also small regions that observe daylights savings WITHIN regions that don’t observe daylight savings WITHIn regions that do observe it. For example, in Indiana it is on a per county basis[1]. 1. https://www.timeanddate.com/time/us/indiana-time.html

Somewhere I have an old book which includes time zone maps for Indiana in the 50s and 60s. Every single year there were changes.

Because there is neither a 12:00 am, nor a 12:00 pm. One is 12 noon, the other is 12 midnight.

AM and PM are "ante meridian" and "post meridian": before" and after. But 12 is on* the meridian; neither one. You can meaningfully say 12:00:01 am, or 11:59:59 pm, but for 12 sharp nobody can say whether am or pm is dark or day.

Airlines schedule flights at 12:01 for this reason.

> (an arbitrary planet that has no impact on the universe whatsoever) What do you call this type of worldview where you just view everything as completely meaningless or devoid of any value? Is it really straight up Narcism? I mean my god no wonder this is one of the most depressed generations on record. Apologies for the off-topic comment, I just felt compelled to post this. We are the most meaningful, most importan…

I like life, but we are meaningless motes in the universe. We'll all be dead one day and no one will remember us. It's ok though, it doesn't matter.

If human matters do not matter, why assume that language carries meaning?

Do you believe that animals have meaningful conversation? Or that humans do?

Does the universe speak? If it did, would you know?

Do you understand its language? Can you hear it?

There's also something else: nothing.
