MIME CurrentDateTime Property

See more MIME Examples

Demonstrates the read-only CurrentDateTime property, which returns the current local date and time formatted as an Internet message date including the numeric UTC offset. The example uses it to populate a Date header field.

let mime = chilkat::Mime::new();
if mime.set_body_from_plain_text("Message with a Date header.").is_err() {
    println!("{}", mime.last_error_text());
    return;
}

// CurrentDateTime returns the current local date and time formatted as an Internet message date,
// including the numeric UTC offset, for example: Fri, 21 Nov 1997 09:55:06 -0600
let now = mime.current_date_time();
println!("Current date/time: {}", now);

// It can be used to populate a Date header field.
let _ = mime.set_header_field("Date", &now);

let Ok(head) = mime.get_entire_head() else {
    println!("{}", mime.last_error_text());
    return;
};

println!("{}", head);
