Sol:- First check NTP service and check it is sync it with client server or not with the below command.
       
        [root@server/]#ntpq -pn

               remote           refid      st t when poll reach   delay   offset  jitter

========================================================================

198.168.200.3    .

▒.            16 u   53   64    0    0.000    0.000   0.000

198.168.200.4    .

▒.            16 u   52   64    0    0.000    0.000   0.000

          Then we need to update the ntpdate with the below command
