Clock auto set via network failed

Dear Sir,
I found the clock network auto setting function is not stable recently. After finishing the clock auto set via network, the correct setting will be updated to be false time about after 10 seconds. Is there any setting files or commands to solve the problem? Thanks.

Dear melinda.hung,

Did you set the clock setting with the following guidance?
https://docs.nvidia.com/drive/active/5.1.0.2L/nvvib_docs/index.html#page/DRIVE_OS_Linux_SDK_Development_Guide%2FInterfaces%2Frealtime_clock.html

And please refer to the link for clock setting topic. Thanks.
