Well, you could force it to work by casting new.ontime to text
explicitly, but this is a pretty horrid way of testing for a negative
interval anyhow. I'd be inclined to do something like
new.ontime < '0 seconds'

BTW, the IS NOT NULL test is redundant too, since the comparison
can't succeed for a null.
