Abstract
Methods, systems, and computer program products for performing differential media time calculation and display are provided. A method includes determining a time of media origination, determining a current time, and calculating a differential media time as a difference between the current time and the time of media origination. The method also includes using the differential media time to determine information update data and outputting the information update data for display.
