Subject: while loop end action

I am trying to write a script that when certain circumstances arise it
creates an object instance that adds some info to a temporary array for
a given time. When the given time is up I would like to perform a couple
actions and print the array.  After that the array and object instance
will no longer be needed, so I would like to ensure the obj is freed
from memory.  I am pretty new to coding and to Ruby, what is the best
way to accomplish this.  I thought it would be a while loop but I am
confused as to how to perform an action once my counter or time has
reached it's end.  For example, where can I put the ending action?

class Blah
  def initialize
    @myarray = Array.new
    @init_time = Time.now.to_f
    @twomin = @init_time + 120
  end

  def add_to_array(x)
    while Time.now.to_f < @twomin
      @myarray << x
    end
    #pp @myarray.inspect
  end

end

Since the while loop has a definite end.  Does this end the object's
instance, I suspect no and I need to put some die statement in there or
delete the object from outside the object?

If I do an if/else loop than it will continue to run I suspect too.
if Time.now.to_f < @twomin
      @myarray << x
else
  pp @myarray.inspect
end

How can I properly run some actions or a method after my counter/time
has reached it's end and then delete the obj instance?

Thanks
