What must you configure so router log message timestamps match the NTP-synchronized/local time?

The service timestamps log datetime localtime command ensures that log messages include a timestamp based on the router's synchronized local time, which is derived from NTP if configured. This is crucial for accurate event correlation and troubleshooting. Waiting longer will not automatically apply synchronized time to log messages; a specific command is needed. The service timestamps log datetime synchronize command does not exist. While NTP provides the time source, service timestamps log ntp is not a valid command for configuring log timestamps. The localtime keyword specifically instructs the router to use the local time, which will be accurate if NTP synchronization is in place.
