 * rejected. Omit this gate when no time restriction is wanted.
 *
 * Future admission searches actual UTC minute boundaries, so nonexistent local
 * times are skipped and repeated times can open the window twice. The search
 * is bounded to 72 hours and the Date range; no opening returns nextCheckAt:null.
 * Historic time zones with second-based offsets may defer up to one extra minute.
 * This gate does not schedule a timer, authorize a destination or send a message.
