Chrono: retrieve the user locale in wasm?

1

Hi,
using chrono, how do we automatically retrieve the current browser's locale to print a nice localized string to the user ?

The date is constructed from a timestamp (i64).

In pure javascript, I do:

const formattedDate = new Intl.DateTimeFormat(navigator.language).format(date);

The issue with the above is that I miss the hours and minutes.

But with the chrono package, I have to give the offset myself. And I don't know how to dynamically retrieve it.

My current try:

    if timestamp_nano == 0 {
        return None;
    }

    timestamp_nano /= 1000;

    match Utc.timestamp_opt(timestamp_nano, 0) {
        chrono::offset::LocalResult::Single(dt) | chrono::offset::LocalResult::Ambiguous(dt, _) => {
            info!("TIME {:?}", dt);

            Some(dt.to_rfc2822());
     
        }
        chrono::offset::LocalResult::None => {
            info!("TIME error");

           None
        }
    }

from the timestamp
Any help ?

Thanks

The answer is:

let h = dt.with_timezone(&chrono::Local).to_rfc2822();

Nice
