TIL: Sweden had February 30 in 1712 https://en.wikipedia.org/wiki/1712_in_Sweden , so I decided to see how chrono handled that.
use chrono::TimeZone;
use chrono_tz::Europe::Stockholm;
fn main() {
let feb30 = Stockholm.ymd(1712,2,30);
println!("Date: {:?}", feb30);
}
target/debug/feb30
thread 'main' panicked at /home/snaggen/.cargo/registry/src/index.crates.io-6f17d22bba15001f/chrono-0.4.34/src/offset/mod.rs:252:40:
No such local time
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Result (as expected): Not well! 😄
I also tested Java with
ZonedDateTime feb30 = ZonedDateTime.of(1712,2,30, 0,0,0,0, ZoneId.of("Europe/Stockholm"));
with simmilar result
java.time.DateTimeException: Invalid date 'FEBRUARY 30'
So, lets take a minute of silence for all the programmers of history related software, may the spagetti monster have mercy on their souls.
Can someone explain the benefit of letting AWS use your product, then throw resources at it to improve it to get and advantage over your product, basically providing a much better product to their users than you would be able to. But they do it without any need to contribute back. I don't see the benefit of this to the opensource community at all, but people here seems to be quite passionate about it so you must see this differently than I do. So, please explain your view on how such a situation is beneficial to the OpenSource community.
