How to set Netapp filer to Sync with NTP server

In the first example below it was set to use RTC ( Real time Clock )

FAS01> options time

timed.enable                 on         (same value in local+partner recommended)

timed.log                    on         (same value in local+partner recommended)

timed.max_skew               5m         (same value in local+partner recommended)

timed.min_skew               0          (same value in local+partner recommended)

timed.proto                  rtc        (same value in local+partner recommended)

timed.sched                  1h         (same value in local+partner recommended)

timed.servers                192.168.0.9 (same value in local+partner recommended)

timed.window                 0s         (same value in local+partner recommended)

To change this to use the NTP server  

FAS01> options.timed.proto ntp

filer0*> options time

timed.enable                 on         (same value in local+partner recommended)

timed.log                    on         (same value in local+partner recommended)

timed.max_skew               5m         (same value in local+partner recommended)

timed.min_skew               0          (same value in local+partner recommended)

timed.proto                  ntp        (same value in local+partner recommended)

timed.sched                  1h         (same value in local+partner recommended)

timed.servers                192.168.0.9 (same value in local+partner recommended)

timed.window                 0s         (same value in local+partner recommended)
