Create two java.util.Date objects (yes, the deprecated ones).

Use the getTime() method on each object to get milliseconds from the epoch.

Subtract the smaller time from the larger time, and then convert to seconds by dividing by one thousand.

1. Convert both to dates using SimpleDateFormat.
2. Get the difference between them by calling getTime() and subtracting one from the other.
3. Divide the number by 1000 to get seconds.
