I want to write these times in a \"hh:mm\"

Answer 1

based on How to add 30 minutes to a JavaScript Date object?

var d1 = new Date ();
var d2 = new Date ( d1 );
d2.setHours ( d1.getHours() + 6 );

https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Date will show how to manipulate Date objects.

added your code with some fixes. edited to add second document.write
