One, time stamp notation

That is, an integer or floating-point type represents a time interval in seconds. The base value for this time is calculated from 0 o'clock on January 1 in 1970.

Two, tuple format notation

That is, a python data structure representation. This tuple has 9 integral types of content. Each represents a different time meaning. If the tuple items are

where DST (daylight Savings time) flag ( -1, 0, or 1) is the daylight saving date format, 0: Indicates normal format, 1: is expressed as daylight saving, 1: Indicates based on the current datetime format

There are two of the proper nouns:

UTC (coordinated Universal time, world co-ordination) is GMT, world standard Time. In China for Utc+8.
DST (daylight saving time) is daylight saving time. is a system for saving energy and artificially set local time, usually early in the morning in the summer for one hour ahead of time. (detailed explanation asked Niang)
