两种时间戳类型
例如s1=1704879917000
 1、13位的时间戳:单位(毫秒)
 
(1)毫秒变成秒,1s=1000ms,s1/1000(秒)
(2)加载时间
times = time.localtime(s1/1000)(3)时间格式化
time.strftime("%Y-%m-%d", times)#格式化后的格式:例如:2024-01-10%Y  Year with century as a decimal number.%m  Month as a decimal number [01,12].%d  Day of the month as a decimal number [01,31].%H  Hour (24-hour clock) as a decimal number [00,23].%M  Minute as a decimal number [00,59].%S  Second as a decimal number [00,61].%z  Time zone offset from UTC.%a  Locale's abbreviated weekday name.%A  Locale's full weekday name.%b  Locale's abbreviated month name.%B  Locale's full month name.%c  Locale's appropriate date and time representation.%I  Hour (12-hour clock) as a decimal number [01,12].%p  Locale's equivalent of either AM or PM.
 2、10位的时间戳:单位(秒)
 
 times = time.localtime(s1)
