Survival mode has converted to creative

I have been playing survival mode. The last time I logged out the game was fine. When I logged back in however the game was in creative mode. I am not sure why, from time to time I change into or out of peaceful mode, this has never been a problem. The date and time the game displays is wrong also........it says 1/1/70.
Have included a couple of screenshots, as you can see from those I have chests in my house, but I can no longer access them. Any ideas guys???????? Thanks. My phone is a HTC Desire S if that counts for anything
