Dart - How to set the hour and minute of DateTime object

Question

How do I set/change the hour and/or minute of a DateTime object. Similar to Date.setHours(..) in JavaScript.

e.g If i did

var time = DateTime.parse("2018-08-16T11:00:00.000Z"); 

how do I set the hour and minute of time

Answer 1

var newHour = 5; time = time.toLocal(); time = new DateTime(time.year, time.month, time.day, newHour, time.minute, time.second, time.millisecond, time.microsecond); 

There were discussions to add an update() method that allows to modify specific parts only, but it doesn't look like this has landed.
