Stone Sudoku

The objective of sudoku puzzles is known to everyone I guess. But if you lived under the rock, you must fill all the blank squares in the game with the correct numbers. There are three very simple constraints to follow. Every row of 9 numbers must include all digits 1 through 9 in any order. Every column of 9 numbers must include all digits 1 through 9 in any order. Every 3 by 3 subsection of the 9 by 9 square must include all digits 1 through 9. Solve it within the shortest period of time and submit your high score! Good luck!
