How do I adjust hours in work day?
 

I created my gnatt chart nicely with omni plan for all my employees and all the tasks for the company. But at the end of it, I realized that there's one thing I need to change which is the number of work hours in a day. Our company only count 7 hours in a day but omni plan assumes 8. I tried changing it in the calendar view but it messed up all my tasks entered. Is there a way to change the number of hours but not mess up all my tasks?

You can change the hours in a work day by going to the "Project : Unit Conversions" inspector.
