i got a new sd card and i installed it manually and everything was working it seemed for a while but when i went to work to work on this it showed wrong time but not date

everytime i try to change time and date it wont save and keep even though i push the right buttons and push save and reboot

i bought this

LoveRPi 8GB Raspbian NOOBS UHS-I MicroSD Card with SD Adapter for Raspberry Pi

So i haveit plugged in but even without it plugged in it went straight to desktop so my pi already has a OS installed so why cant i make it save the time and date and why isnt this os working ???

The timezone is set for mine central and it doesnt change neither does the date what is going wrong

I bought this monitor for it being thin and with speakers for a magic mirror i hope to make. (hope is the key word)

I want to remove the bezel if it will make the mirror more flat. But my question is will it be hard to remove and if anyone can give pointers.

That doesnt help much sorry

Im unsure how to even add modules or anything as it does nothing now

P.S. im starting with android mirror since the rasp pi would be to hard to do

I want to make my mom a magic mirror but idk how to do modules to save my life it is very tricky and all i have is the app and it doesnt even display holisays lr birthdays what do i do im so lost
