PPC30 - 30993 Time jumps

Hello, I am using into a system a PPC30.0702_23B.

The time changes automatically without a clear explanation. The CPU is working at 20% and NTP synchronization is not active.

I have 2 panels with same software. Only one of them has this issue.
The Only difference between them is Automation runtime:
B4.62 for the one that works fine
J4.93 for the one with timeJumps.

I read the topic with the Timejump in a Hypervisor system where the problem was in windows but I do not think i cave the same case here.

Any idea can help.

Thank you!

PPC30 is not hypervisor system. So it has no relation to this topic, you are right with this statement. Can you share with us printscreen of your NTP configuration as well as what is used as a CPU timer? Do you have in your logic of visualization task for time change implemented?

I have in VC4 the numeric inputs directly connected to Internal.DateTime where i can change the time.

For now I changed the automation runtime version to B4.62. It is ok until now but I am waiting for longer time to conclude.
Thank you for your time!

If only AR version change makes this difference, then please get in contact with local B&R support and report it.

I marked your last answer as a solution, but feel free to change it if you will figure out new findings. Thanks.
