The patch are mostly documentation changes.  The code changes are all related 
to output messages.  So I did not add new unit tests.

Tested Util.millis2String(long) manually as shown below:
{code}
  public static void main(String[] args) {
    long n = (1L << 32) - 1;
    System.out.println(Util.millis2String(n));
  }
{code}
Before the patch, the output is "49 days 17:02:47.-01"  which is incorrect.
After the patch, the correct value, "49 days 17:02:47.295", is printed.
