Which Qubes version? There is no setting for that, but it should be possible to "break" time sync mechanism quite easily. On 4.0, Windows do time sync only using own NTP client, so you can disable just that. On 3.2, there is qubes.SetDateTime service, which you can disable by renaming "c:\Program Files\Invisible Things Lab\Qubes Tools\qubes-rpc\qubes.SetDateTime" to something else. - -- Best Regards, Marek Marczykowski-Górecki Invisible Things Lab A: Because it messes up the order in which people normally read text.
