+== Time-based retention validation
+
+Redpanda introduces timestamp validation controls to improve the accuracy and reliability of xref:manage:cluster-maintenance/disk-utilization.adoc#set-time-based-retention[time-based retention]. The new properties `log_message_timestamp_before_max_ms` and `log_message_timestamp_after_max_ms` ensure that messages are accepted only if their timestamps fall within a valid range. This prevents retention issues caused by invalid or out-of-range timestamps.
