The author presents what Sandy did on a weekday morning through a time order, describing a series of actions according to a sequenced order. To describe something according to the order of time is especially common with narrative writing. From the reading passage we can find that the presentation of details clearly follows the progress of time, as is apparent from the following words or sentences. 
The beginning sentence of the story tells us about the time: The radio clicked on. This is a very strong reminder of the time. From the passage we find that it was 6:15 A.M., time for getting up. After a couple of events, we find that after her shower, the conversation went on and something more happened. Then suddenly she looked at the clock again; it was late, still a strong indication of the time passing. And at last she ran to catch the school bus, which tells us that Sandy left for school. The time marker is expressed through the action of leaving.
