Creating a DateTime from epoch milliseconds

[nevi-me]

I've been able to convert a DateTime to milliseconds with timestamp_millis(), but I am struggling to find a trait member that allows me to get a DateTime with milliseconds.

Is it currently possible to do this?

[govo]

So, we need to convert millis to nanosec first?

Possible way

use chrono::{DateTime, TimeZone, NaiveDateTime, Utc};

fn main() {
    let time  = chrono::Utc::now();
    let ts_millis = time.timestamp_millis();
    println!("timestamp milli {} -> {}", time, ts_millis);

    let ts_secs = ts_millis / 1000;
    let ts_ns = (ts_millis % 1000) * 1_000_000 ;
    let dt = DateTime::<Utc>::from_utc(NaiveDateTime::from_timestamp(ts_secs, ts_ns as u32), Utc);

    println!("timestamp milli {} -> {}", dt, dt.timestamp_millis());

}

Could we add a DateTime::from_timestamp_millis(millis: i64) for this?

I'm open to reviewing a PR for that.

Wouldn't it be better if it were u64 as in DateTime::from_timestamp_millis(millis: u64) than i64?
