This depends on what a system is used for. A few seconds off may be fine for one purpose, but a significant problem for another. Similarly a sudden (however small) change to the TSC tick rate may be a problem for one purpose, but not for another. If otoh (and just to give an example) it was determined that the TSC tick rate on a physical system varies over time within certain boundaries, then leveraging this to change (slowly, i.e. with no steeper a gradient than might be observable on bare hardware) the rate to match the new host's might be an option. Emulation then could be turned off after a certain period of time.
