Should I file a bug report? 😀

TIL: Sweden had February 30 in 1712 https://en.wikipedia.org/wiki/1712_in_Sweden , so I decided to see how chrono handled that.

 rust

    
use chrono::TimeZone;
use chrono_tz::Europe::Stockholm;

fn main() {
    let feb30 =  Stockholm.ymd(1712,2,30);
    println!("Date: {:?}", feb30);
}

  

 undefined

    
 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

 java

    
ZonedDateTime feb30 = ZonedDateTime.of(1712,2,30, 0,0,0,0, ZoneId.of("Europe/Stockholm"));
 

  

with simmilar result

 undefined

    
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.
