Quiz Results Search Error

Excellent! Works great!

I am testing VQuiz and have noticed an error in the search results while attempting to create a list to export. For example, I have a test quiz that was completed on April 19th. When I enter the date range of April 19 to April 19 to see only ones done that day I get no results.

However it I make the end date the day after, it then shows the correct filtered list showing only the quizzes on the day prior.

Hopefully the attached image illustrated what I mean. My question: Is this the inherent way the date range works? So if someone wants to see quiz results on a certain day the end date needs to be the day after?
