Program Time takes an Eastern Standard Time in hours, minntes, and seconds and prints it out in Eastern Time, Central Time, Mountian Time, or Pacific Time, Again, the program compiles but the answer is wrong Correct the program describe the error, (hint: this bug is very subtle-you neef a good test plan to find it.)
