Time and date

[Dale 1977]

We have an android phone at work and someone removed the battery, now the phone won't let us update the date and time.
Done all the things it says online about turning off auto and doing it manually however when we do that and put it to today's time and date and press ok it then goes back to 2015, any ideas would be appreciated

Welcome to Android Central! Which phone? Is this a phone that has a user-removable battery, or did that person have to take the phone apart to remove it? I am assuming, of course, that the battery has been reinserted.
