Was correct at the time, but has since been addressed by
qemu/qemu@105fad6bb2, which added support for set-time without a time
argument, as used by `virsh domtime --sync` by libvirt-guests.sh. I can
confirm that `virsh domtime --sync` works correctly on a Windows 10
guest, as does `SYNC_TIME=1`. (Note that there can be a significant
delay between when the command completes and when the guest time
finishes synchronizing due to QEMU GA calling `w32tm` with `/nowait`,
which complicates testing.)
