  • are you only get the seconds from the epoch to the current data every time? If so you can just call System.currentTimeMillis() / 1000 Commented Aug 1, 2011 at 20:25

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.
