Concurernt request end-date dafault at 23:59:59

Hi,

I am creating a concurrent program with two parameters that allow users to select a date range (From and To).
If a user wants to select orders for a single day, they would enter the same date for both From and To.
However, because the default time for dates is set to 00:00:00, no results are returned.
Is there a way to set the "To" date's time to 23:59:59 automatically?

Thank you!
