IPv4 address of the peer providing or being provided with the clock
synchronization.
(Optional) Defines the Network Time Protocol (NTP) version number,
where the number argument is a value from 1 to 4. The default is 4.

is specified in seconds as a power of two. The number is used in a
power-of-two (for example, 2 meaning 2
4 to 14. The default value is 6.
(Optional) Defines the longest polling interval, where the interval argument
is specified in seconds as a power-of-two. The default value is 10.
(Optional) IP source address. The default is the outgoing interface.
(Optional) Interface type. For more information, use the question mark (?)
online help function.
(Optional) Identifies a physical interface or a virtual interface.
