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.
