this should either be setVirtualTimeEnabled(bool) or should not exist at all and
policy should have an additional "disabled" value. Sorry, only looked at this
file.

I know where you're coming from but I'm not sure it makes sense to disable
virtual time. The virtual time base may get far ahead of real time which means
posted timers could get "stranded in the future".
