You need to configure the NTP on the ESXi and point it to a server NTP server NIST Internet Time Service or if you have a domain controller which acts as a NTP server you can configure that server as NTP for the ESXi.
For the VMs you can enable or disable time synchronization with the host. If you have in your network a server that acts as a NTP you can configure that server in centos as NTP server. If not, you can synchronize time with the ESXi host from the VM properties > Options > VMware Tools and there you will see the option.
