The batter is out no matter what. In this case, he is out because of the third strike, and in this instance the umpire can call the runner out also. Remember that the strike out came first followed by the interference.
If the batter had not struck out but interfered with F2, then the batter is out for the interference. Time would not be called unless the throw by F2 was unsuccessful in retiring the runner. If the throw was unsuccessful, then the runner would be returned to 1B.
I hope that I'm making sense.
