Hello Dan,
I attached a screen shot.
Meantime I figured out that this is the due time of the entry.
I work with due time to see at work what tasks I need to do while I am at work (due in the morning) and what tasks I have to do in the evening.
I have a new suggestion:
Add an option in the calendar where I can select to see all calendar entries in full width (like the second entry at Saturday in the screen shot) and where I see the due time as text in front of the entry.
Example: 9:00 Buy Milk
I searched for a screen shot of this feature (Outlook) and here it is:
Greetings
