To automatically keep the system time synchronized, you need the name of at least one time server. NetApp recommends that you supply the name of more than one time server in case one becomes unavailable.
Specify up to five time servers in the order they should be contacted by the time daemon. Use either IP addresses or the server names. If a server cannot be contacted, the time daemon tries the next server in the list.
The default value for the Servers field is the null string.
