Markets in time

…[the Chicago White Sox] have just announced
that for the next three seasons, their evening home games will begin at
7:11 p.m. instead of the customary 7:05 p.m. or 7:35 p.m.  Why?  Because
7-Eleven, the convenience store chain, is paying them $500,000 to do so.

That is from Stephen Dubner.
