I want to use Coarse Universe selection at a specified time not 0:0. How I can modificate CoarseUniverse to change the time when the filter function is triggered.

I want to use 

public IEnumerable<Symbol> CoarseSelectionFilter(IEnumerable<CoarseFundamental> universe)

to filter my universe.

I want to trigger the universe filtering function at 9:30 AM to filter all gappers equities.


Thanks for answers.
