Timestamp is represented as chrono::Duration

Internally Timestamp is represented as i64 describing number of milliseconds since unix epoch. Driver converts this to chrono::Duration

When sending in a query it needs to be wrapped in value::Timestamp to differentiate from Time

fn main() {
extern crate scylla;
extern crate chrono;
use scylla::Session;
use std::error::Error;
async fn check_only_compiles(session: &Session) -> Result<(), Box<dyn Error>> {
use scylla::IntoTypedRows;
use scylla::frame::value::Timestamp;
use chrono::Duration;

// Insert some timestamp into the table
let to_insert: Duration = Duration::seconds(64);
    .query("INSERT INTO keyspace.table (a) VALUES(?)", (Timestamp(to_insert),))

// Read timestamp from the table, no need for a wrapper here
if let Some(rows) = session.query("SELECT a FROM keyspace.table", &[]).await?.rows {
    for row in rows.into_typed::<(Duration,)>() {
        let (timestamp_value,): (Duration,) = row?;
