So I've tried the trick from Virtual PC 2007, adding the following section to the vmc configuration file:

<components>
    <host_time_sync>
        <enabled type="boolean">false</enabled>
    </host_time_sync>
</components>

Later someone suggested VPC doesn't want the components level so added this instead:

<host_time_sync>
    <enabled type="boolean">false</enabled>
    <frequency type="integer">15</frequency>
    <threshold type="integer">10</threshold>
</host_time_sync>

When I start up XP Mode (Microsoft Virtual PC) it completely ignores any of these two configuration changes and if I change the clock it's instantly reset to the host time again. I've also obviously disabled the Windows Time service but as it's not joined to a domain or set up with a source it shouldn't be involved anyway.

I need to test an application over a few midnight passes and thought the XP Mode machine would be perfect, so I didn't have to mess with my workstation clock... is there any way to get the VPC guest to not sync time with the host? This is easy in Hyper-V ;p
