I was fighting with timepicker's default settings. The default settings were overridden somehow. Then, I noticed that they were actually overridden by Pods Framework's code:
var pods_form_ui_pods_field_baslangic_tarihi_args = {"timeFormat":"h:mmtt","dateFormat":"mm\/dd\/yy","ampm":true};
I would like to change the default settings of date and time formatting. How can I do that?
