The standard timing coincidence apparatus is altered to utilise electronic collimation for determination of the depth-of-interaction (DOI) contribution upon the timing performance of a scintillator detector. No relationship between the coincidence time resolution (CTR) and DOI is observed for multiple scintillator crystal materials, wrappings and geometries.   #It %It  is shown that DOI information can reduce the CTR by upto 20\%, compared to standard coincidence measurements, for wrapped 30mm scintillator crystals.
