we have now tried everyting: disable time syncs between host and guest, use windows time service, dont use it - results are still the same: every now and then, the event log shwos events from the kernel with id 1 stating "the system time changed to ... from ...". It always adds time, and it always adds something between 1 minute 17 seconds to 1 minute 35 seconds of time. There is no obvious reason for that, the server is productive, not overloaded, not going into sleep mode, just a plain webserver. But it is crucial that these time leaps disappear.
any help much appreciated. thank you,
