> I was looking at the code done for ACCUMULO-3221 and noticed that we're using the system clock instead of the JDK's internal relative time, System.nanoTime(). This is a problem, because any auth timeout that depends on the system clock can be easily bypassed by changing the system time.
> We can also do the time conversion more reliably with {{TimeUnit}} to avoid the potential arithmetic bug identified in ACCUMULO-3221.
