Configure a Virtual Machine to Synchronize Time with the Host in the vSphere Web Client

You can configure a virtual machine to synchronize the guest operating system time with the host time.

When you enable this setting, VMware Tools checks once per minute to make sure that the guest operating system time is in sync with the whether the guest operating system time is lagging behind the host operating system time. If it is, the guest operating system time is moved forward to match the host operating system time.

Regardless of whether you enable this setting, time synchronization occurs when the VMware Tools daemon is started (such as during a reboot), when resuming from a suspend operation, and after shrinking a disk. When the operating system starts or reboots, synchronization can be either forward or backward in time. For other events, synchronization is forward in time.

Prerequisites

■	Ensure that the guest operating system is not using another method of time synchronization, such as NTP, before enabling time synchronization with the host.
■	Power off the virtual machine before editing the VMware Tools options.
■	Required privilege: Virtual machine.Configuration.Settings

Procedure

Select a virtual machine.

■	In the virtual machines and templates inventory tree, select a group of virtual machines and select a virtual machine from the list on the right.
■	Search for a virtual machine and select it from the search results list.

In the VM Hardware panel, click Edit Settings.

Click VM Options.

Click the VMware Tools triangle to expand the VMware Tools options.

Select Synchronize guest time with the host.

Click OK.
