Work hours not respected

[sevyb]

Hi there
I have defined in the general settings work hours from 8:00 to 18:00. But when I add a new entry starting at 8:00, the calendar view shows me also 7:00 and 7:30. I get a warning when I try to enter an event before 8:00, but I can do it. I would like to disable the automatic adding of hours or, if not possible, to block the possibility of adding events outside the work hours. How can I do this?
Best regards
Yves
