Simple timing method I end up rewriting a lot

time.scala

  def time[T](msg: String)(f: => T) = {
    val start = System.currentTimeMillis
    val v = f
    val end = System.currentTimeMillis
    println(s"[TIMING] $msg: ${java.text.NumberFormat.getIntegerInstance.format(end - start)} ms")
    v
  }
