Mobile: Change text format date time in Input

In my mobile app I have a form with an input bound to a DateTime variable as shown below.

The default behavior of this input (at least in the browser emulator) is that that the DateTime format is "MM/dd/yyyy hh:mm tt". This is not how we want to represent the DateTime in our application, it should be "yyyy-MM-dd HH:mm"  (time with 24 hour format)

Is it possible to force this format in the input box?

Instant edit: I found this post but that does help me any further as this is for web development using RichWidgets nor do I want to change the global server settings because of a business wish for one app:
