We have studied the relative-time dependence of the {ital CP}-violating asymmetry obtained by tagging the charged leptons in the {ital B}{sub {ital d}}{sup 0}-{ital {bar B}} {sub {ital d}}{sup 0} mixing on {Upsilon}(4{ital s}). For the eight quark subprocesses and their {ital CP}-conjugate processes, time-dependent {ital CP}-violating behaviors are examined. We have found that the {ital {bar b}}{r arrow}{ital {bar c}c{bar s}} ({ital b}{r arrow}{ital c{bar c}s}) and {ital {bar b}}{r arrow}{ital {bar c}c{bar d}} ({ital b}{r arrow}{ital c{bar c}d}) processes are most spectacular and the {ital {bar b}}{r arrow}{ital {bar u}u{bar d}} ({ital b}{r arrow}{ital u{bar u}d}) and {ital {bar b}}{r arrow}{ital {bar u}c{bar s}} ({ital b}{r arrow}{ital u{bar c}s}) processes strongly depend on the unknown Kobayashi-Maskawa (KM) matrix element {vert bar}{ital V}{sub {ital ub}}{vert bar} and the KM phase.
