Is the modern "instant" the same as the ancient "instant"?

The original day and night was divided into 100 minutes, which was changed to 96, 108 and 120 minutes successively because it was not divisible with twelve o'clock, and it was officially set as 96 minutes in Qing Dynasty. In this way, one hour is equal to eight quarters. A moment is divided into three points, and a day and night has twenty-four points, as opposed to twenty-four solar terms. Note that this minute is not the current minute, but a word. Between two moments, two strange symbols are engraved, so it is called "word". The bottom of the word is divided by lines as thin as wheat awns, which is called "second"; The word "two" consists of "he" and "Shao", where he refers to wheat and Shao refers to tiny awns. You can't row below seconds, you can only say "as thin as spider silk", which is called "suddenly"; For example, the word "suddenly" suddenly refers to a very short time, but it refers to change, which means change in a very short time.

Now the daily day and night is 24 hours, while in ancient times it was 12 hours. When western mechanical clocks and watches were introduced into China, people called the time points of China and the West "Da Shi" and "Shi Shi" respectively. With the popularity of clocks and watches, people forget "Da Shi", and "Shi" is still in use today.

The unit of measurement below hours is "hours". One hour is divided into eight hours, and each hour is equal to fifteen minutes now. There is a saying in the old novel called "chop at noon three times", that is, chop at noon three times (fifteen minutes away from noon), when the yang is flourishing and the yin disappears instantly. This heinous crime should be "not even allowed to do ghosts" to show severe punishment.
