The resulting Hour and Second was twice as long as ours.
We are currently precessing into the Age of Aquarius, from Pisces.
Making up your own "facts" does not make them true. That the Egyptians determined a day by the amount of daylight and the longest day of the year (June 21) has 14 hours, 4 minutes and 57 seconds of daylight negates your claim that the hour was "twice as long as ours". Particularly since 1/12th of an equal period of daylight would give an hour of 70.41 minutes. The shortest day of the year, December 21, would give an equal period of daylight (10 hours,m 12 minutes 40 seconds) divided into a further equal period of 12 hours of 51.05 minutes. Nowhere near dooubled as you'd like others to believe. And the shortest period of time, the at (moment) as mentioned by kmt_sesh, bears no specific designation of length of time in AE society and therefore does not open it up to interpreting it any way you wish.
The zodiac as determined by the Greeks is irrelevant to the period of the builders of the Great Pyramid as Egypt had not such zodiac. Which makes the Greek zodiac meaningless in this discussion.
