dates are all wrong

[rodic66]

First click on text box, get this

select 18/01/2017 - text box displays correct value.

Now the wierd stuff happens. Click on text box again.

See what happened, whole month of January shifted back in time to one day earlier and Jan 17 is selected, current date Fri Jan 20, 2017 , I know it by the fact that there is presidential inauguration is going on, but according to a calendar it is Fri Jan 19, 2017, and plus when I click on, lets say 15/01/2017, 16/01/2017 is displayed in text box.
That is a real shame, it is very good looking and easy to integrate datepicker. I'm pretty sure there is something wrong in the moment.js, since ng-flat-datepicker is just an angular wrapper, still very disappointed.
