Prerelease 6.4rc10b - Time/Clock not correct

[Magnusri]

Hello!

 

I am a fairly new user of UnRaid. I am running two gaming Windows 10 VMs on my host machine. This has been working flawlessly until the point i installed 6.4rc10b, and started getting wierd computer times in the host OS, and the VMs. (Both VMs and host can have different clock times..)

 

Both of the VMs seem to run the clock very slowly.. In a few hours, they are usualy about 20 mins behind real-time. 

 

 

What have i tried to fix the problem:

1. Set VMs to not update time from timeserver within windows (manual date/time)

2. Changed timezones on Host and VMs

3. Changed timesync server on Host

 

None of my solutions has made any change to the problem..

Has this problem been encountered before, and does anyone have any suggestions?

 

Thank you

Magnus

I would suggest that you post up your diagnostics file with your next post.   (  Tools   >>>   Diagnostics   )  Someone may spot something that is going on. 

 

Perhaps, someone who is running a Windows VM might comment about their experience with time keeping accuracy. 

 

You might also report the issues that this problem is causing you.

Wonder if your CMOS battery is low. Could be the polling interval for Unraid is just 1 time per day and it gets that out of sync beforehand. Something to check.

I have exact same problem, CMOS battery is fine but exact same symptoms.

I have two Windows VMs and both display the correct time. It is required though to set the correct time zone and check if DNS works for the VM so it can resolve the NTP server address.

Thank you for the suggestion. As i wrote, i have changed the timezone and disabled and re-enabled the automatic time servers om both VMs and host machine. This sets the time correctly, but the time is still passing "slowly", loosing about 8 seconds every 3 minutes.. 

 

About the CMOS battery, i could try changing it however it is very unlikely to be running low. The Motherboard is 2 months old, and has only been for sale for about 4 months.. 

 

I am now running Dimension 4 time sync software on both VMs. It keeps the machines usable by syncing the time every 3 minutes. 

 

Will post my diagnostics in a few hours

I don't know what is causing your issue, but in my case the time stays accurate for both VMs.

Same, I have 3 VMs always on and date/time stay correct, not much help but it's probably something related to your hardware/config.

You might list your hardware and any details om any type of overclocking.  (I recall that you are using it a 'gaming machine.)

The machine is used for gaming, yes. It has the following spec:

 

i9 7900x cpu 10core

ASUS Prime x299-a motherboard

2x geForce 1080ti

512gb M.2 Samsung 950 evo ssd

512gb Samsung 850 evo ssd

32gb HyperX Fury

 

No overclocking on anything
