How to manipulate system time?

[Jet]

How do I move the system clock forward without leaving the app that is in the foreground? I'm using a rooted android 7.1.1 device for testing. For example I want to configure it to move time forward 12 hours from the current time and date when the flow is activated. Time should move forward into the next day(s). For example it's 12PM and I move time forward 13 hours, the new date and time should be the next day 1AM.

I tried getting chatgpt to create a superuser shell command block or a version for non rooted devices using privileged shell command block but nothing is working. I can start/stop the flow using a interface or button press trigger so activating the flow is not an issue. Also a time reset command to Automatic date and time toggle on and back off would be helpful as well. Someone please help, I am dumb.
