RFC 3339 requires an offset, so ajv-formats already rejects a naive \"2026-07-20T19:30:00\" — while also accepting fractional seconds and lowercase \"z\" (both valid, both rejected by the obvious regex) and rejecting 2026-02-30T19:30:00Z (which the obvious regex accepts). Verified against ajv-formats 3.0.1."
