This document contains the code for a Java GUI application that allows a user to enter two times and calculates the sum of the times. It defines the layout of the GUI with labels and text fields for the hours, minutes, seconds of two times as well as labels and fields to display the sum. It also defines buttons to calculate the sum, start a new time entry, and exit the application. The code sets up the event handlers for the buttons and text fields.
