My iPod 5 shows the incorrect time and date.

My iPod touch 5th generation will not display the correct time or date. No matter what I do, it changes back to December 31, 1969. I know this is usually a error that corrects itself, but it has not for 24 hours. My iPod is up to date, but says I need to update to iOS 8.0.2, even though I have already done so. When I try to re install it, it says the update is unavailable.

I have done the following:

Reset/turned off the iPod

Tried to manually set the date and time, but no matter how far I go it snaps back to December 31, 1969 7:00 PM

Set the time and date automatically (it gives me a loading symbol for forever)

Closed out everything and reset the wifi

Charged it on a computer with the correct date

And this problem is still here. I can't message anyone, update certain websites or email, and Messages always crashes. My Time Zone is correct, too.

Can anyone help??
