I am trying to figure out a way to get my phone to use 2 different ringtones based on the time of day. What I want is to have the phone to vibrate between 5 pm and 1 am when I am at work then go to a regular ringtone after that. I accomplish this now by setting the profile to vibrate at 5 pm then when I get off work set the profile to normal. What I am looking for is an automated way of doing this so I don't have to physically do it twice a day.
