A question then: you change the parameter to MIN() to no longer have 
'now' added to it. Because both values are supposed to be relative not 
absolute. If that's the case, should we be subtracting 'now' from the 
result of MIN()? We currently do, and your patch does not change that. 
So it seems a bit odd to me.
