Change ntp server without reboot

What Unity box is this?. Can you raise a SR for this?.

If you want to try yourself, you can try to adjust the time with little difference (say 15 mins from current time) - repeat this several times until the time is close to the NTP servers time.

To check the difference from unity ssh login:

00:37:51 service@none-spa spa:~> ntpdc -c sysinfo X.X.2.25

Above example, the local time is 2841 seconds (47 minutes) behind ntp time.

Using unisphere GUI, increment the time to 15 mins (many repeats required) until the time is with in 10 minutes of ntp server (Below is full example using uemcli)

00:45:20 service@none-spa spa:~> uemcli -u admin -p pass  /sys/time set -utc "2016-10-12 1:30:00" -force noReboot <-- too much diff, failed because, it requires reboot

Operation failed. Error code: 0x60008f5

A reboot is required to set the Date and Time. Please use the reboot dialog box from the GUI or specify allowDU/allowReboot option from the CLI to reboot and set the time. (Error Code:0x60008f5)

00:46:28 service@none-spa spa:~> date; uemcli -u admin -p pass  /sys/time set -utc "2016-10-12 1:00:00" -force noReboot
