This allows to use the RTC as accurate reference clock inside the guest, specifically if the host time is smoothly following an accurate external reference clock, e.g. via NTP. -If you want to isolate the guest time from the host, even prevent it from -progressing during suspension, you can set @option{clock} to @code{vm} instead. +If you want to isolate the guest time from the host, you can set @option{clock} +to @code{rt} instead.
