Simple cron like scheduler in Scala

Today in my Scala explorations I ran into the problem that I wanted some scheduler like Quarz or java.util.Timer -- that should be easy in scala I thought an came up with the following:

private val timedActor = actor {
    //once a day
      while (true) {
      performTask
      val c = Calendar.getInstance
      c.set(Calendar.HOUR_OF_DAY, 0) //midnight
        c.set(Calendar.MINUTE,0)
      c.add(Calendar.DAY_OF_YEAR, 1) //next day
        val sleepAmount = c.getTimeInMillis - Calendar.getInstance.getTimeInMillis
      Thread.sleep(sleepAmount)
    }
}

Pretty slick heavy weight (check the comment for a better implementation) -- they should include that in one of their libraries...
