Scheduler ViewType days - BeforeCellRender : Wrong start - end

With the scheduler when property "ViewType" is set to value "Days" we have a problem with the following event : "OnBeforeCelleRender".

• aspx

OnBeforeCellRender="BeforeCellRender"

• Code behind

protected void BeforeCellRender(object sender, DayPilot.Web.Ui.Events.BeforeCellRenderEventArgs e)
{
e.InnerHTML = e.Start.ToShortDateString();
}

e.Start and e.End will always stay at the same values of the first line.

This bug appears is present in :
6.7.2410
6.4.2251.0
but not in :
5.4.1722.1
