Currently, when using specific DateTime formats, Mendix seems to be adding punctuation to DateTimes. Here's an example:
In the format example, there is no punctuation.
However, when running the application where the user language is Dutch, the following appears:

When selecting a different language such as English (UK), the period is removed:
To address this issue, I would propose not adding any punctuation to DateTimes. As punctuation can still be added manually (either in the default datetime settings of an entire language or in the widget itself), this should allow for more customizability.
Cons / risks
Existing applications may have to manually add punctuation where it was formerly implicitly added
