DESCRIPTION:Directed theories of time maintain that time has an objective 
 'future' direction. In this talk\, I illustrate a sense in which such theo
 ries are incompatible with special relativity. My conclusion follows almos
 t immediately from a particular choice simultaneity relation for a uniform
 ly accelerated observer. I prove that\, in a certain natural sense stemmin
 g from the work of Malament (1977)\, this is the unique simultaneity relat
 ion available to such observers.
