We have checked with your query and we would like to let you know that our DatePicker component will be rendered based on the place holder value set initially through “placeholder” API. While change the locale at the run time, it will accept the placeholder value set through “L10.load” method. This is the default behavior of the DatePicker component.
If you want the initial time DatePicker behavior for run time, you don’t specify the placeholder value in L10.load method.
Please let us know, if you have any concerns on this.
