I need to identify a specific time, but not a specific date. My goal is to say, at midnight on "this date" the patient was at this location.
"This date" = minimum(lastfullmonth)+1

I get 4/2/2014 for my date, but I need to add the midnight time frame and be able to calculate on it.

I was using this formula for the entire date but they want to know exactly at midnight where the patient was:
{@Start} <= minimum(lastfullmonth)+1
   and
{@End} >= minimum(lastfullmonth)+1

Any help would be great.
