I see this option on the MonthView but not on the day view. If I have customers in the military it may be nice to have the dayview timeslots viewed in 24 hour format. Is there not a global setting for this?
It uses the system setting (DateTimeFormatInfo.CurrentInfo.LongTimePattern). If you like you can visit http://devcenter.infragistics.com/Protected/RequestFeature.aspx and submit a request for the ability to change this via a property setting..
