I have Netbeans 6.7 on the Mac Os X platform and its quite an ordeal to get it to install gems without putting it in the wrong directory because it executes installation that requires installation using sudo and does not prompt for the password, so stuff gets installed in the wrong directory.

To start with the last point: the setter methods are engineered to
look like and behave like assignments. So when you do this:

   obj.x = y

it always returns y. It's emulating assignment semantics:

   x = y   # always returns y

So using 'return' with an argument in those methods doesn't work.

As for your main question: I'm not sure whether this does exactly what
you want (though I've got some tests that suggest perhaps it does),
but here's a version that might at least give you some ideas:

require 'time'

class Thing
   attr_reader :created_at

   def created_at=(new_time)
     if new_time == new_time.to_s
       now = Time.now
       str = "#{new_time} #{now.strftime('%H:%M:%S')}"
       @created_at = Time.parse(str)
     else
       @created_at = new_time
     end
   end
end

The idea, as you can see, is to piece together a string that contains
the year, month, and day from the string that was passed in, plus the
hour, minute, and second from Time.now. I think it does what you want
with correct input, though some further checking for correctness might
be in order.
