Slight rephrasing:
To even prevent the RTC from progressing during suspension, you can set
@option{clock} to @code{vm} (virtual clock). @samp{clock=vm} is
recommended especially in icount mode in order to preserve determinism;
however, note that in icount mode the speed of the virtual clock is
variable and can in general differ from the host clock.
(omitting the reference to -icount auto etc.)
