Yes, you don't need to use Qt::String at all in QtRuby. Everywhere you see a 
QString parament in the C++ api you can use a ruby string and it will be 
automatically converted. Also the value of $KCODE is used to correctly 
convert to and from a unicode QString, according to the current ruby string 
format. 

This should work fine:

 class Thing < Qt::Widget
    ....
 def  paintEvent(e)
      #s = Qt::String.new('aweeee') #Time.now.strftime('%H:%M'))
      p = Qt::Painter.new(self)
      0.upto(5) do |n|
        p.drawText(50,50*n, ".")
      end
      s =   Time.now.strftime('%H:%M')  #<--- line 45
      p.drawText(250, 20, 50, 25, Qt::AlignRight, s)
      p.drawLine(20, 50, 280, 50)
      p.end
    end
 ....
 end
