In a grid (let's say todo) :

 

- reproduce/copy the same date in several items -- use the same date field, displayed as a column in the grid.

 

- Add different times (hours and minutes) to the dates in each item.

 

- Right click on the date column & sort ascending/descending : it doesn't sort properly.

Confirmation?
