Gavin,

Yes, de-reference is time variant.

David: The statement above doesn't invalidate the requirement that 
Linked Data URIs have to be de-referencable. The de-reference 
characteristic != what happens at data access request time, since all 
data access calls on the Web are based on the time variant nature of 
actual data state.
