Time Synchronization issue


hi guys,

having in our organization 2 dcs in vm (vmware). in dc (pdc) getting below events event id 50. 

the time service detected time difference of greater 5000 milliseconds 900 seconds. time difference might caused synchronization low-accuracy time sources or suboptimal network conditions. time service no longer synchronized , cannot provide time other clients or update system clock. when valid time stamp received time service provider, time service correct itself

when check command w32tm /query /status getting below output.

c:\users\w32tm /query /status
leap indicator: 3(last minute has 61 seconds)
stratum: 3 (secondary reference - syncd (s)ntp)
precision: -6 (15.625ms per tick)
root delay: 0.4493613s
root dispersion: 0.2010621s
referenceid: 0x7b6ce106 (source ip:  123.108.225.6)
last successful sync time: 5/21/2015 1:02:26 pm
source: 1.asia.pool.ntp.org,0x1
poll interval: 6 (64s)

when check on secondary dc (no roles) same command.

c:\users\>w32tm /query /status
leap indicator: 0(no warning)
stratum: 4 (secondary reference - syncd (s)ntp)
precision: -6 (15.625ms per tick)
root delay: 0.4801178s
root dispersion: 1.0339886s
referenceid: 0x0a0a161f (source ip:  10.10.22.31)
last successful sync time: 5/21/2015 12:59:30 pm
source: dc-01.domain.com
poll interval: 10 (1024s)

keep in mind time settings kerberos default set 600 seconds , long domain machines in limitation fine.
