CHAPTER 3 Using VMware Tools
91
Synchronizing the Time in the Guest with the Host
Operating System
The VMware Tools service can synchronize the date and time in the guest operating
system with the time in the host operating system once every minute. To enable time
synchronization for a Windows guest, see Setting Options with VMware Tools on
page 78. To enable time synchronization for a Linux or FreeBSD guest, see Setting
Options with VMware Tools on page 84. To enable time synchronization for a NetWare
guest, see Setting Options with VMware Tools on page 87.
Synchronizing Guest Time in Response to System Events
The service synchronizes the date and time in the guest with the time in the host in
response to various system events. These events include when you
• Take a snapshot. In the virtual machine’s configuration file (.vmx), this setting is
represented by the time.synchronize.continue option.
• Revert to a snapshot. In the virtual machine’s configuration file (.vmx), this
setting is represented by the time.synchronize.restore option.
• Resume a suspended virtual machine. In the virtual machine’s configuration file
(.vmx), this setting is represented by the
time.synchronize.resume.disk option.
• Shrink the virtual disk. In the virtual machine’s configuration file (.vmx), this
setting is represented by the time.synchronize.shrink option.
Disabling Time Synchronization
If you want to completely disable time synchronization in the guest, open the virtual
machine’s configuration file (.vmx) in a text editor and set the following options to
FALSE.
tools.syncTime
tools.synchronize.restore
time.synchronize.resume.disk
time.synchronize.continue
time.synchronize.shrink
