Q: Is any solution to january 1st 1970 in iphone?

Make a Genius Bar Appointment and have the phone looked at: http://www.apple.com/retail/geniusbar/

I am also a sucker that fell for this

Nice co-worker you have there. They knew that they were bricking your phone. I would report them to HR as this is not just a funny joke that is reversible. Your only option is to take it to an Apple Store.

There are some who fixed it using DFU

I took it to the Apple Store and they were able to restore it to the original settings
