-The '**Enable NTP client** checkbox allows you to enable or disable NTP service. If the service is enabled then the system will periodically synchronize the time with the specified servers.

-If you do not have access to external NTP servers, but you want to make the WebHMI NTP server on the local network so that all other devices synchronize their time on it, then turn on the Provide NTP server checkbox and clear the list NTP server candidates. In this case, WebHMI will synchronize with the real-time hardware clock and provide its local time for NTP clients.+If you do not have access to external NTP servers, but you want to make the WebHMI NTP server on the local network so that all other devices synchronize their time on it, then turn on the **Provide NTP server** checkbox and clear the list NTP server candidates.
