The analysis process is as follows:

A moment means time. In ancient times, time was measured by clepsydra. A day and night is divided into one hundred minutes, and an instant is 14.4 minutes. At the beginning of the Qing Dynasty, it was set at 96 minutes, and an instant was 15 minutes. Today, clocks are used to measure time, that is, 15 minutes.

From this we can get: a moment = 15 minutes.

Time unit conversion relationship:

1 year = 12 months (flat year and leap year 13 months); 1 quarter =3 months; 1 week =7 days; 1 day =24 hours; 1 hour =60 minutes; 1 min =60 seconds.

The transformation of ancient time units in China:

(1) A nail is 60 years.

(2) 1 month = 30 days; 1 day =2 days = 10 days; 1 Wait =5 days.

(3) 1 min = 15 min; 1 =5 minutes (usage in southern Fujian and Guangdong).

(4) 1 night =5 more; 1 more =5 points; 1 point =24 minutes.

(5) 1 hour =2 hours.
