However, I'm still using an acient script running ntpdate 0.de.pool.ntp.org && hwclock --set --date "$(date "+%a %b %d %Y %r")" on a desktop PC and never experienced an issue. As long as the clock is only advanced or, as in my case, sometimes put back a few seconds, I don't see any risks. As far as I know, it's only risky if you set the clock back a long time and then, for example, sync files. Regards, Ralf
