//! The clock, the id generator and the one RFC 3339 spelling this module
//! writes — in one place, on the pattern of `module-notifications`' own
//! `clock.rs`.
//!
//! Every stored timestamp is `Rfc3339` with the sub-second part dropped,
//! because lexicographic order on that spelling is chronological order,
//! and that is what every `next_attempt_at` compare in the drain relies
//! on.
