Today I visited a customer that wanted to enable the VMware tools timesync during an automated install of a Windows VM. The customer didn’t want to use powershell / perl or anyother SDK enabled tool. So what’s left?

“C:\Program Files\VMware\VMware Tools\VMwareService.exe” –cmd “vmx.set_option synctime 0 1″

So this command ticks the checkbox for timesync via VMware Tools, which can come in handy when doing RIS alike installs.
