Function serialize 

pub fn serialize<S: Serializer>(
    value: &DateTime<Utc>,
    serializer: S,
) -> Result<S::Ok, S::Error>

Serialize a timestamp with exactly three fractional digits and a UTC suffix.

The official client interprets fractional digits as milliseconds. Chrono’s automatic microsecond precision can otherwise shift a parsed client date.

Errors

Propagates errors from the serializer.
