Abstract
A 1152 channel timing system used with a large electromagnetic calorimeter is described. Analysis of the timing information from the vertical and horizontal elements of the calorimeter yielded values for the position coordinates of the showers. This information was used to resolve ambiguities in the pattern recognition arising from multiple showers. A resolution of better than 0.25 ns for all channels was achieved. The calibration methods employed to maintain this resolution over several years are discussed.
