ngx bootstrap + angle 6 + date picker

Hello,

I use Datepicker from ngx-bootstrap for the first time and encounter some difficulties.

One of them is that if I choose the desired date, my input is in the exact format that I need, as follows: & # 39; 20 / 12/2018 & # 39 ;, but when I play in the console, the input value is represented as follows: & # 39; Thu 20 December 2018 23:26:21 GMT-0200 (Brazilian Summer Time) & # 39 ;.

How do I leave the input value in Brazilian format: & # 39; 20 / 12/2018 & # 39 ;. I searched for the documentation and did not find it.

Proof of how it works (wrong).
