perhaps, but its not the way you mean. a photon is it's own anti-particle so a feynman diagram shows it as a wavy line with no arrow, that is it is traveling both directions in time. However, if you look at it as traveling back in time the particles become their antis...
p ~~(photon)~~ !e
under t symmitry becomes
e ~~(photon)~~ !p
but the entropy only increaces in one direction "the arrow in time"
