How to construct an OffsetDateTime from ymd+hms

[nicholasbishop]

Hi, I'm trying to figure out how to make an OffsetDateTime from ymd and hms values. Basically the equivalent of this in chrono: Utc.ymd(2010, 1, 2).and_hms(3, 4, 5).

I see I can construct the two parts separately like Date::from_calendar_date(2010, Month::January, 2) and UtcOffset::from_hms(3, 4, 5), but didn't find a constructor or conversion function that would allow them to be combined into an OffsetDateTime.

UtcOffset::from_hms(3, 4, 5) creates an offset from UTC, not a time.

What you're looking for is:

Date::from_calendar_date(2010, Month::January, 2)?
    .with_hms(3, 4, 5)?
    .assume_utc()

Assuming you want UTC to be the offset. If not, you'll want to use PrimitiveDateTime::assume_offset.

If these values are statically known, I suggest you use the macros instead:

datetime!(2010-01-02 03:04:05 UTC)

Perfect, thanks!
