NTP Service
You can have your Synology NAS serve as a network time server to synchronize time between different network devices and the Synology NAS over network.
To enable the NTP service:
Tick Enable the NTP service and click Apply.
Note: The NTP service is required for Surveillance Station and high-availability cluster. Therefore, if you have Surveillance Station or High Availability Manager installed and run on your Synology NAS, the service cannot be disabled while the package is running.
