We present a measurement of the time-dependent asymmetry in the rate for {bar B}{sub d}{sup 0} versus B{sub d}{sup 0} decays to J/{psi}K{sub S}{sup 0}. In the context of the Standard Model this is interpreted as a measurement of the CP-violation parameter sin(2{beta}). A total of 198 {+-} 17 B{sub d}{sup 0}/{bar B}{sub d}{sup 0} decays were observed in p{bar p} collisions at {radical}s = 1.8 TeV by the CDF detector at the Fermilab Tevatron. The initial b-flavor is determined by a same side flavor tagging technique. Our analysis results in sin(2{beta}) = 1.8 {+-} 1.1(stat) {+-} 0.3(syst).
