why date on lock screen suddenly went back and not allowing to enter the phone ?

[WPCentral Question]

after a gap of 5 hours my phone was showing screen lock asking to enter pin number. I have entered the pin and it returns back a message stating try again after 1 minute and i did so. this time it asks to try after 2 minutes .. and then suddenly some 6000 minutes and again 191508 minutes.. what went wrong and how to get it solved. even the date on the screen is four days old (28 sep ).even a change of sim card is of no use.

I had that once on my titan, my son entered the wrong number and it was locked for 5 mins and in that time it went flat turned it back on and the date was wrong and when I worked it out I had to wait 12 years to get into it again.

Only solution my friend its a hard reset sorry!
