I haven't seen anything like that, VirtualBox doesn't step the time if my
Windows laptop does to sleep and wake up. On my laptop, VirtualBox
V7.0.6 seems to enable hpet by default, since it show up as enabled in
the logs.

The NTP daemon doesn't seem stable in this envvironment. The drift
file has -1.498 in it.
