Python3日期与时间戳转换的几种方法详解

import datetime
import time
# 获取当前时间
dtime = datetime.datetime.now()
un_time = time.mktime(dtime.timetuple())
print(un_time)
# 将unix时间戳转换为“当前时间”格式
times = datetime.datetime.fromtimestamp(un_time)
print(times)

import datetime
import time
# 字符类型的时间
tss1 = '2019-06-03 21:19:03'
# 转为时间数组
timeArray = time.strptime(tss1, "%Y-%m-%d %H:%M:%S")
print(timeArray)
# timeArray可以调用tm_year等
print(timeArray.tm_year) # 2019
# 转为时间戳
timeStamp = int(time.mktime(timeArray))
print(timeStamp) # 1559567943

import time
timeStamp = 1559567943
timeArray = time.localtime(timeStamp)
otherStyleTime = time.strftime("%Y-%m-%d %H:%M:%S", timeArray)
print(otherStyleTime)

import time
import datetime
timeStamp = 1559567943
dateArray = datetime.datetime.utcfromtimestamp(timeStamp)
otherStyleTime = time.strftime("%Y-%m-%d %H:%M:%S", timeArray)
print(otherStyleTime)
