<p>QDT has no escape path for 0. The constructor calls setRemainngTime(0), which calls setPreciseRemainingTime(0, 0), which will get the current time, add zero, and store it.</p>
<p>After all of that, the QDT should return that the remaining time is zero, since it's expired.</p>
<p>remainingTime() calls remainingTimeNSecs(), which calls rawRemainingTimeNSecs(), which should return a negative value. remainingTimeNSecs() should detect the negative and return 0; remainingTime detects the zero and returns it.</p>
