I take issue with this. The second before was -1 seconds from the epoch. Null 
is the absence of a value, so you can't get to null by simple arithmetic. I 
learnt about negative numbers from the Greeks. And no, I'm not going to comment 
on their current mathematical difficulties.



But the point still stands: -1 !== null.
