Windows 10 auto time set problem

Hello,

I'm using Windows 10 Pro as a VMware 10.0 guest and I don't want the guest to automatically re-synchronize its time of day clock from the host, Internet, or anything else.  Instead, I want to merely set that clock then have it keep time from that starting point.  I've gone into the Win10 date and time settings and turned off the "Set time automatically" feature and I've also disabled automatic time setting from the Internet.  I then set the clock to the desired time and it works fine as long as I don't reboot.  However, after a reboot the clock goes back to the same time as the host clock. How do I stop this resynchronization?

Thanks,

Ray
