Not sure why I couldn't reproduce it on my amd64, but this does not fail after I stop systemd-timesyncd. Well, you managed to find it on GKE, which is not ppc64el, so good enough.
stime and settimeofday should not be fiddling with hwclock, only system time. Maybe we should stop systemd-timesync for anything that has time in it?
