Ok, here's what I put together to use the rtc on the nextion to sync the arduino.. Then it can be easily formatted and manipulated. Someone may have a better or easier way but I have not found it yet.. I use the Arduino Time library by Michael Margolis. enjoy!
No such thing as improved Nextion.
After trying this program, I see that I have mcu errors: data overflow What should i do knowing i have nextion hmi improved with arduino mega2560
