I was having the problem where I tried to change the date and time on my VPC environment, it keeps resetting it back. To resolve the issue, you need to edit the *.VMC file and add the highlighted section below, resave the file and launch your VPC.

<integration>
    <microsoft>
        <mouse>
            <allow type=”boolean”>true</allow>
        </mouse>
        <components>
            <host_time_sync>
                <enabled type=”boolean”>false</enabled>
            </host_time_sync>
        </components>
