Wrong Date and Time

I went to the calendar format and it was on Buddhist!! If your calendar is messed up and says BE, it's on buddhist which is why it is all messed up... Man i'm a genius (that was sarcasm)

I was also experiencing this problem, however my calendar was not set to the Buddhist calendar like some people have mentioned, so that fix was not an option for me. I will say though, I had not used my ipod touch in a while so the battery had been completely dead before I plugged it in, turned it on, and noticed this issue with the date and time. I say that because I had read one of these posts that someone said they left their ipod charging for a while before they tried messing with it, and it was back to normal by the time they came back to it once it charged.

After plugging it in while I fiddled with it, I first tried resetting default settings (NOT a full wipe) with no success. I then tried to sync it with iTunes, as mentioned above, and I did not think it worked at first because the date & time were still wrong, and I was waiting for it to perhaps automatically change itself back. However, a couple minutes after I had synced it with iTunes, I again tried to manually change the date & time and it finally let me with success, whereas before it would not and would just revert back.

I'm not sure if the date & time got screwy simply because the battery had died a while back and had not been turned on since, therefore just needing to charge for a few minutes... or if the sync method is actually what did the trick. In any event, it's back to normal and working properly again.
