Flip clock on javascript

Hi!
I find very fine flip clock project and want add it to my habpanel. But it write on pure javascript and convert it to angular impossible for me.
Can I insert this code to habpanel without convert to angular?

I think I solved my problem. I write html file and put it in static folder. In Habpanel Frame widget I use URL to this file: http://192.168.0.10:8080/static/index.html
It work without angular.
