HI Sir，

As the phone do not contain a battery in it, so it can not save the manually configure time. That is by design.

Are you verifying the time is set correctly on-device and via the exported config? Not just the web-gui option?

In my experience, when provisioning a specific time, it is not uncommon for the web-GUI will not reflect the settings you provisioned but if you export the config, you can see it was set correctly and working just fine.

Perhaps set the time and check again.
