You don't need to use a Calendar instance. Here's a simpler solution:

long millisStart = System.currentTimeMillis();
// run your query here
long millisEnd = System.currentTimeMillis();
System.out.println(millisEnd - millisStart);

Calendar cal = Calendar.getInstance();
long millisStart = cal.getTimeInMillis();
// run your query here
cal = Calendar.getInstance();
long millisEnd = cal.getTimeInMillis();
System.out.println(millisEnd - millisStart);
