In real life researchers in the Arctic at or near the North Pole use {{w|Coordinated Universal Time}} as the [http://www.thoughtco.com/the-north-pole-1435098 local time standard] by convention, to avoid this exact problem. Thus it could have been said that Emily was born on the date that it was at that time in UTC. Furthermore, it is extremely unlikely that she would have been born at the exact instant the plane was over the north pole, indeed, it is unlikely that the plane even traveled over the exact pole, as opposed to a few miles or even feet to either side of it. With modern positioning equipment such as GPS, it should have been possible to determine which time zone the plane was in when she was born. Even in the impossibly unlikely event that she was directly above the pole at the instant of her birth, at jetliner speeds the plane was traveling about ten miles per minute, so a reasonable delay of even seconds in declaring "time of birth" would have placed the plane and her clearly in one time zone. | In real life researchers in the Arctic at or near the North Pole use {{w|Coordinated Universal Time}} as the [http://www.thoughtco.com/the-north-pole-1435098 local time standard] by convention, to avoid this exact problem.

Edge pieces are generally only important with sheet goods (brownies sheet cakes, etc), which are typically cut into pieces creating a difference between pieces originating on the edge and pieces originating from the center. Since the sides of a cake are often frosted, an edge piece has two faces covered in frosting and a corner piece has three, while a center piece only has one. Depending upon your relative preferences between the surface (often icing over marzipan) and core body of the cake (which can be fruitcake, or some variety of spongecake, etc, but not actually obvious which until the cake is cut), it being an edge-faced slice can be considered a bonus. Cueball certainly seems to appreciate this. |
The title text states that the {{w|IERS}} sends Emily a cake every time they add or remove a leap second, out of superstition (perhaps Megan is delivering that cake). The International Earth Rotation and Reference Systems Service is in charge of global time standards. It occasionally adds one leap-second to {{w|Coordinated Universal Time}} to adjust for changes in the rotation speed of the Earth. | The title text states that the {{w|IERS}} sends Emily a cake every time they add or remove a leap second, out of superstition (perhaps Megan is delivering that cake).
