Update user experience for the date with time column

When updating a date with time column, once the date is chosen the calendar popup closes, making it so you have to choose the time first, then the date. That’s fine, however, if you need to choose a date other than today, you choose the time, choose the date, but in choosing the date, it overrides the time entry to 9:00am and closes the calendar window, making it so you have to click on the date again to open the calendar and update the time. Very inefficient.
