In version 1.5.6 it worked absolutely sufficient. Background: we (industry OEM, paying for VirtualBox licences) are using a data acquisition program as VirtualBox guest (host=Win XP(e), guest = Win XPe). Using VirtualBox 1.5.6 time synchronisation is fine, the acquired trend data do not show any interruption. After updating to VirtualBox 1.6.0 (for test purposes) we get an unusable time delay of the guest machine. The time delay of the guest is resynchronised after some minutes, but the data trend lines aquired every second get an interruption when automatic resync is done. We need a guest time differing less than one second of the host time! This is a killer criterion for our future using of VirtualBox! martl" defect closed guest additions VirtualBox 1.6.0 fixed time resync Windows other
