Many times we forget to put our cell phone on silent mode, and then it rings in the work place disturbing others and putting you in a troublesome situation (college students). This flow will change the profile or mode of the cell phone from Ringer mode to Vibrate on the specified time and vice versa. Suppose your college starts at 800 hrs, this flow will change the mode into vibrate mode at the time specified say 730 hrs. Then if your college ends at 1500 hrs, flow will go back to the ringer mode at the specified time; say 1500 hrs.
