Recently we had the requirement to create a Generic Inquiry and Report with parameters to filter on a date range using both date AND time to account for multiple labor shifts.
I could not identify a schema field that included a time component, so I created two additional string parameters for the time components. I then parsed the time parameter and added the corresponding number of minutes to adjust the start and end dates in the GI/Report condition. I also had to make an adjustment for UTC, which works differently between the GI and the Report.

It seems a bit hacky, but it does do the trick. Has anyone else encountered this requirement and possibly found an easier method to provide the functionality?
