I rarely ever use the date command, but when I need it I almost always struggle to get the right incantation. So, wrote a blog post for easy reference.

Do you use a cheatsheet as well?

    LLMs do this pretty well. I’ve used them for date/time formatting strings across a number of languages.

        The other “real person” who replied to me told me that the Linux date command has nothing to do with formatting.

          Second sentence of the description from the man pages, “Otherwise, depending on the options specified, date will set the date and time or print it in a user-defined way.” not sure what they were on about.

            Right - I’m just saying that it’s super annoying that people point out times that llms have been wrong as though humans are never wrong, or even aren’t wrong frequently.

              I get that. It’s funny I think I’ve gotten advice in the past to always check the results of search engines because they can be wrong (as in teachers said it to me) or things about Wikipedia being unreliable. But nobody does those things nowadays. Perhaps someday LLMs will be good enough that we don’t need to check them either.

      date is the command for setting the system date and time from the command line. Nothing to do with formatting, beyond the fact that it presumably applies system locale settings when echoing date-time info.
