On Postgres, timestamp('created_at') maps to a JavaScript Date; adding mode 'string' returns the raw driver string and skips parsing. The default column type is timestamp without time zone, so no offset is stored and the Date is interpreted using the process time zone, which differs between a developer laptop and a UTC container. Declare withTimezone true to get timestamptz, which is almost always what is wanted.
SQLite has no timestamp type at all. There, integer('created_at', { mode: 'timestamp' }) stores epoch seconds and mode 'timestamp_ms' stores milliseconds. Mixing the two across a codebase produces dates in 1970 or in the far future, and neither errors, so pick one convention and assert it in a test that round-trips a known instant.
