Even the latter may be a problem. I have a Win8 laptop that I
occasionally boot to Sid, and of course it's an hour out back on Win8.
But it is set to use NTP, however, there seems to be no control over
how often it updates, and it certainly doesn't do it on boot. I always
give up and use the admin password to trigger a sync, as a normal user
can't do it.
This seems to be the most likely answer, basically, add your own
cron-equivalent job to do it independently of the Windows *once* *a*
*week* scheduling.
