I imagine Blue Prism may update this in the future. But I think the best way to deal with this is to suggest the update to Blue Prism and then just always use UTC for inputs to the Work Queues object's actions.
I agree that it is not intuitive that it is UTC and is annoying.
The way I handle this is to use the function Now() instead of Today. If you want to use Today in UTC, which either doesn't have a time or the time output equals 12:00:00 AM, then you can use ToDate(Now()), which will output something like '10/10/2019 12:00:00 AM'. This is in the case that you are trying to pull data from the queue since this morning.
And you can also just cast Now() into a Date data item or even a Date input parameter, and it will cut off the time so that it comes out to '10/10/2019' or whatever your date format is.
