Solution:so we must have the both node as NTP clients clock synchronized with NTP server from USA. 1.Install package (which Time:dgram Time:stream would use)

$ pkg Install/service/network/legacy-network-services

2. Create the NTP client configuration file on the nodes.

$ touch/etc/inet/ntp.conf $ chown root:sys/etc/inet/ntp.conf 3. Edit the ntp.conf, set the sync time server on both nodes. Vi/etc/inet/ntp.conf ADD The following line to ntp.conf file.

Server 10.134.151.1 prefer

Note:here Our nodes ' s IP is 10.134.151.xx,so we can add our router IP to the above file. 4.Ensure that slewing option

/usr/sbin/svccfg-s svc:/network/ntp:default SetProp config/slew_always = True
svcadm Refresh SVC:/NETWORK/NTP: Default 

5.Restart services on Nodes:wrote a shell sript--rssmf.sh:

#! /bin/sh
svcadm Disable Svc:/network/ntp:default
svcadm enable Svc:/network/ntp:default
svcs-a | grep time
svcadm Disable Time:dgram
svcadm enable Time:dgram
svcadm disable Time:stream
svcadm enable time: Stream
Sleep
ntpq-p

Note:ntpq-p would output the following results:

root@itqe-t5-2-2-ld1:~# ntpq-p
     remote           refid      St T when poll reach   delay   offset  jitter

See the front appear *,offset continuously become smaller, then work normally. 6.Test the time syc with date. refenece:[http://blog.csdn.net/jacky0922/article/details/8535402
