I know just about every cell phone out there now has some sort of call timer built into it. Most phones calculate the number of minutes used during a call, the total used over the phone's lifetime, and they usually have another timer that you can reset whenever you please.

What I want to know is if there are any phones out there that let you key in when your off-peak time begins and ends. Then when you make the call the phone increases an off-peak or on-peak timer depending on when you are making the call. It's not easy to remember when you made your calls when thinking about your off-peak minutes vs. on-peak.

Anyone seen a phone like that?
