Playing times don't have to mean anything anyway. In the European cups, a team can only participate in one. If you're in the Champions League for example, you don't play in the UEFA cup unless you get knocked out in the 3rd qualifying round, even if you might be qualified to play in both due to having won both a national championship (qualifies for Champions League, actually as many as the top 4 teams do for certain countries) and a national cup (qualifies for UEFA cup, as does being runners up for a champions league place).
So they're mutually exclusive here, even if a team could play both in theory.
