Shorter Days

It is spring, and the Sun is above the horizon longer and longer each day. On the other hand, Earth's rotation has increased slightly by the recent earthquake in Chile, making each day a little shorter. While the annual shift in daylight is noticeable, the change due to the earthquake is not. According to NASA, the shift was only about a microsecond. This is a length of time that I cannot imagine, it is so short. Nevertheless, it is a fun little fact to know of.
