[Clay glances over, and... you know, he's about to go on to another fact, but he tilts his head a bit and pauses. This is something he'd like to answer, one that goes along with his line of thought.]
The International Earth Rotation and Reference Systems Service, or IERS, monitors the Earth's rotation. They determine a time scale based on the current rate of rotation of the planet. It's thanks to them that they discovered a time frame that goes all the way back to the 1820s, and they estimate that when the Earth was first formed, it only had a 6.5 hour day and night cycle. Some scientists believe that wind and changes in atmospheric pressure is a contributing factor to this.
