Dates in a custom format are not updated in day headers if the cxFormatController.UseDelphiDateTimeFormats property is set to True

[DevExpress Support Team: CLONED FROM B203112: Dateseparator incorrect if date format is German]
The Problem is still present with DevExpress VCL v14.x controls under Delphi XE7:

Calling TcxSchedulerDateTimeHelper.DayToStr(now, 0, false) gives 'Freitag, 13/ November' on a German language system
while DateToLongDateStr(now) gives correctly 'Freitag, 13. November 2015'

Calling cxFormatController.UseDelphiDateTimeFormats := true; beforehand also corrupts the call to DateToLongDateStr. Both functions use cxGetDateFormat().

It seems like the date formatting functions inside cxDateUtils.pas do not replace the special character '/' in the format strings with the current user's DateSeparator.

The other linked issue B203525 is not the same problem.

Just another remark: I tried your current Feature Demo and the dates in the Scheduler are also wrong.

Thank you for your report. I have reproduced this behavior with German settings in modern IDEs and forwarded this ticket to our developers for research.

I'm sorry, but your last update didn't fix the issue. After installing v15.2.3 I can still find the wrong separators in our application. Thus I installed your latest demos and there the problem is also present (see screenshot attached).

Hello,

In the context of this ticket, we have fixed the issue that prevented the solution from the B203525 ticket from working correctly. I mean the following code that can help you display correct German dates:

Code
uses  
...  
  cxFormats, cxDateUtils,  
...  
initialization  
 FormatSettings.ShortDateFormat := cxGetLocalShortDateFormat;  
 FormatSettings.LongDateFormat := cxGetLocalLongDateFormat;  
 cxFormatController.GetFormats;

We understand that the current Scheduler behavior with German date formats need to be changed, but for now we have not found a way to do so without breaking other regional formats. We are going to continue our research and will try to find a solution in the context of the T340069 ticket.
