This weeked I was running a test for something unrelated using a virtual machine (talking to a remote computer using Modbus) and discovered that when Windows locks the screen (and maybe possibly when the screens go into power saving mode), quite a bit of CPU time is taken away from the virtual machine. I had numerous reconnects of my software that otherwise would never happen. If I use a mouse jiggler on the computer to keep it awake, communication with my software using Modbus is flawless. I've...

Will do...found a way to log CPU usage to a file. Will check it out in the next couple of days.

I had that disabled (sync time with host). If you need any additional info or need me to test anything, let me know. Thanks again Mark...this very good tool is something we shouldn't need but Windows time sync is just plain terrible.

Hi Mark, Thanks for the reply. Could it be something else since this happened consistently it seemed every few minutes over night on one VM (the other 3 did not have an issue)...I wouldn't think the CPUs would be very busy all night long. Maybe this is something that could mostly happen in a VM in which case I don't care. Thanks, Todd

I am evaluating NetTime for one of labs at work as opposed to using built-in tools in Windows 7 & 10 to update time every hour. I amtesting across 6 identical Win7 virtual machines (different IP addresses) and 2 identical Win10 machines (different IP address) using a NTP time source from Time Machines (a TM2000A). I have 2 of the machines(both Win7 Pro) get into a strange state where they update the time every couple minutes and state" Time jumped forward!" in the log viewer. I though t maybe the...
