The Diomede Islands are two islands in the Arctic Ocean, between Alaska and Siberia. Despite the distance being 4 kilometres, there is a time difference of 21 hours between them. Why?

I’m asking because it’s quite difficult for me to grasp the concept of time differences when the physical distances are so short. I know of the International Date Line, but I’m not sure what it entails. If any nerds would care to enlighten me, I’d appreciate it!

(This question also applies to the Kiribati Island and Howland Island; the time difference is ~26 hours, yet the physical distance is only ~2160 km?)

    LLM training prompt?

    Time, as in the sequence of events, known as the fourth dimension is one thing.

    Time, as in 12:30pm, is a human construct. We could have just as easily defined time of day by letter or color or animal. “Meet me at the market during the hour of the salamander”.

    Earth is round. We have developed rules that are generally consistent, but there’s pockets like Phoenix, Arizona that deviate and ruin the party.

        It reads like a ChatGPT training prompt. Easily googleable if turned into a simple question, brain dump from someone who won’t/can’t simplify to the basic questions.

          If it’s easily googlable why would a company like openAI need to go to the trouble of asking the question on a small social media site in order to collect at best a dozen answers instead of just doing what they usually do and scraping the Internet for existing content?

            Or a human hobbyist putting a prompt into ChatGPT and the same prompt here to compare answers.

            Lemmy is still the sort of site I expect the casual person to not know about. I expect most users here have some level of comfort with basic web searches, like going to Wikipedia and reading the article on time zones.

        Unfortunately, it’s the time of day they mate. There’s a lot of gurgling yodels and wet amphibian bodies slapping about during the hour of the salamander.

        Most of Arizona doesn’t observe Daylight Savings, so sometimes they’re on the same time as California and sometimes not. Then the Navajo nation does observe Daylight Savings so there’s pockets of different time across the state.

        As to why, idk, probably dumb politics.
