diesel::expression::dsl::now cannot be used with diesel::pg::types::sql_types::Timestamptz

[andy128k]

I'm trying to execute following query:

        diesel::update(session.filter(key.eq(new_session.key)))
            .set((
                data.eq(new_session.data),
                accessed.eq(now),
            ))
            .execute(&connection)
            .unwrap();

Here accessed is Timestamptz field.

It doesn't compile and I receive

expected struct `diesel::types::Timestamp`, found struct `diesel::types::Timestamptz`

As a workaround I copied-and-pasted now and redefined Expression

pub struct NowTz;

impl Expression for NowTz {
    type SqlType = Timestamptz;
}

...

but it would be nice to have built-in solution.
