The nephilim blooded were said to have 6 fingers and toes. I believe our time system comes from the sumerians. Gilgamesh was the leader of the Babylonian empire during the tower of babel. He was believed to be 1/3 nephilim and 2/3 human. So it would be safe to assume there were other nephilim blooded at that time. After all, the Canaanites were giants who had to descend from somewhere. Months are divisible by 6, the hours in a day, minutes in an hour, on down to seconds. It's 6s all the way down.
