Is there something like TimeSpan in android development?

android

Solution

public long addSeconds(long dt,int sec) //method to add seconds in time  
{

    Date Dt = new Date(dt);
    Calendar cal = new GregorianCalendar();

    SimpleDateFormat sdf = new SimpleDateFormat("MM-dd-yyyy HH:mm:ss");
    sdf.setCalendar(cal);
    cal.setTimeInMillis(Dt.getTime());
    cal.add(Calendar.SECOND, sec);
    return cal.getTime().getTime();

}

pass date and time in sec, it will return modified time...

Problem
