Date format on xElements

[idrenn]

Hi Dear.
I'm using the library in objective-c and everything is going fine but how can I change the date format of the dates of the xElements?

My problem is: I need consistency in date format like if I set date format (08/10/2019 12:30:20) then this format will be shown all the time.

But right now Date format is changing, at the start of entries it shows only time then date/time and after somedays, it shows the only date.

Thanks.
