使用python实现1970年秒数和datetime互相转换

1. 获取当前那时间的时间戳

	import time
 	time.time()

2. datetime转1970年秒数

	import time,datetime
	timeDateStr="2018-12-22 00:00:00"
	time1=datetime.datetime.strptime(timeDateStr,"%Y-%m-%d %H:%M:%S")
	secondsFrom1970=time.mktime(time1.timetuple())

3. 1970年秒数转datetime

	import time,datetime
	timeArray = time.localtime(1342483456)#1970秒数
	print(timeArray)
	otherStyleTime = time.strftime("%Y-%m-%d %H:%M:%S", timeArray)
	datetime1=datetime.datetime.strptime(otherStyleTime, "%Y-%m-%d %H:%M:%S")
