Virtual machines have a virtualisation of the physical machine's clock.

Most software timing does not use the RTC, except at boot up, although I seem to remember that there is an option of using the RTC for ntpd and a virtual machine's RTC is more likely to reflect the underlying physical machine's RTC than the software clocks are to track each other.

To the extent that there are legal requirements, I feel that is an issue that the virtual machine environments need to address, not somthing they should force onto the users.
