Configuring time synchronization with VMware virtual servers

Synchronizing with PingFederate servers instead of the default internet time service can solve synchronization errors in Windows Virtual Machine servers.

Before you begin

Install VMware Tools on your guest OS. For more information, see .

Steps

  1. Go to Control Panel → Set the time and date → Internet Time tab → Change settings…​ and clear the Synchronize with an Internet time server checkbox.

  2. Open Command Prompt as an administrator.

  3. Enter time to verify that the host time is correct.

  4. Set the following .vmx configuration option to enable periodic synchronization.

    tools.syncTime=true

    By default the server will synchronize time every minute. Use the following command to change the synchronization frequency.

    tools.syncTime.period=time in seconds

Troubleshooting

VMware Tools time synchronization cannot correct the issue if the guest OS time is ahead of the server. In that case, use NTP or w32time to set your server clock.
