Time sync with NTP on Vmware Fusion VM

I built a Centos 6.9 VM in VMware Fusion with Synchronize Time turned off and I followed this doc:



https://kb.vmware.com/s/article/1006427?sliceId=1&dialogID=373948728&docTypeID=DT_KB_1_1&stateId=1+0+373966292



However, I still have the problem when I pause & resume the VM, the clock is still off as it doesn't resync automatically.



This is what I have:

The only way to sync time is to run:

Any idea how to fix this?

                I decided NOT to use NTP but use Vmware Tools instead.



                vi /etc/yum.repos.d/vmware.repo

                [vmware-tools]
                name=VMware Tools for Red Hat Enterprise Linux $releasever - $basearch
                baseurl=http://packages.vmware.com/tools/esx/latest/rhel6/$basearch
                enabled=1
                gpgcheck=1
                gpgkey=http://packages.vmware.com/tools/keys/VMWARE-PACKAGING-GPG-RSA-KEY.pub

                sudo yum install -y vmware-tools-esx-nox
