Specifies the IP address of the NTP server to allow for clock synchronization. ip_address must be specified using the standard IPv4 dotted decimal notation.
Specifies the minimum polling interval for NTP messages, in seconds, as a power of 2. poll_period is the power or exponent. For example, if you specify the number 10, the value is 2^10 and the resultant poll period is 1024 seconds.
poll_period must be an integer from 6 through 17.
Specifies the maximum polling interval for NTP messages, in seconds, as a power of 2. poll_period is the power or exponent. For example, if you specify the number 10, the value is 2^10 and the resultant poll period is 1024 seconds.
poll_period must be an integer from 6 through 17.
Important: Adding, removing, or modifying an NTP server configuration entry causes the NTP client to restart and restart the synchronization process with all configured NTP servers.
