I guess you can't go backwards into yesterday on the on-line
listings sites--at least not with zap2it.com.
A starting place to check would be WCBS-TV New York. What
did they yesterday at 12 and 12:30pm ET? Since Y&R is fed
12:30-1:30 ET for the east coast, and if the bowl coverage
started at 1, what did CBS air at 12:30?
This of course is all further complicated by the split feed of
Y&R to the Central zone (12-1 ET/11-12 CT), and the fact that
the bowl game goes "live to all stations" meaning 11 MT/10PT.
