What exactly to you mean when you say it is "not working"? Your formula, using CTRL+SHIFT+ENTER to commit it, works for me. I will note that the formula outputs a time serial value (that is, a floating point number) which requires the use of Cell Formatting in order to select a proper time display format for the value.
