//! Timestamp seeding must match the column's own type.
//!
//! `created_at`/`updated_at` are seeded from the clock, but the seed was hardcoded to
//! `Utc::now().naive_utc()` regardless of what the column actually is. A `timestamptz`
//! column resolves to `DateTime<Utc>`, so the seed was the wrong type and both `Default` and
//! `new` failed to compile — 1638 errors across the live schema.
