I have problems with Gant graph (Projects->Gant).
It doesn't display time project properly.
I've got defined many tasks with diferent start, end time in my project, so my project time should start with earliest task and finish with the latest, but on Gant "start date" and "finish" are the same and looks like project takes only one day...
How can I resolve this problem?

Have you tried changing the dates with the little calendar button?

In Modules->Project->gantt.php (near 30th row) in SELECT is:

ti.task_end_date AS project_actual_end_date

In my opinion should be:

max(t1.task_end_date) AS project_actual_end_date

Otherwise it doesnt't work right.
