Changing the format of the WInCC Digital/Analog Clock

I have inserted a "WinCC Digital/Analog Clock" and I want to change the display in Runtime.

I want to be displayed in DD/MM/YYYY and the time in 24 hour clock.

Although,the formatis changedin the according pdl (LocaleID => 1031 or 1081), it doesn't change in the Runtime.

Is there any idea?

Thanks in advance in your time
