answer: Don tells from the sun that it's not time for lunch yet, but Harriet tells #Person1# it's already past noon, then Harriet explains to him the principle of measuring time.
documents: #Person1#: What time is it, Harriet? I'm starving, but I guess it's not time for lunch yet.
  #Person2#: Let's see. According to my iphone, it's just a few minutes past noon.
  #Person1#: What? I thought my watch was wrong. Shouldn't the sun be overhead if it's noon?
  #Person2#: Oh, Don, I can tell you weren't listening in science class last week. The sun is only overhead at noon for 2 days a year.
  #Person1#: Haha, very funny.
  #Person2#: No, really. Mrs. Sorenson explained it. The Earth goes around the sun at an angle and that changes where the sun is at noon.
  #Person1#: But then those old clocks that measured time by the sun shadow were all wrong.
  #Person2#: Emm, not exactly. They're just not the same as the time we keep on our computers.
  #Person1#: I wish I was sitting in a computer right now instead of out here. I'm starting to hate nature.
