1、获取秒级时间戳与毫秒级时间戳
import time
import datetime
t = time.time()
print (t) #原始时间数据
print (int(t)) #秒级时间戳
print (int(round(t * 1000))) #毫秒级时间戳
nowTime = lambda:int(round(t * 1000))
print (nowTime()); #毫秒级时间戳，基于lambda
print (datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')) #日期格式化
返回
1499825149.26
1499825149
1499825149257
1499825149257
2017-07-12 10:05:49
2、将日期转为秒级时间戳
dt = '2018-01-01 10:40:30'
ts = int(time.mktime(time.strptime(dt, "%Y-%m-%d %H:%M:%S")))
print (ts)
返回
1514774430
3、将秒级时间戳转为日期
ts = 1515774430
dt = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(ts))
print(dt)
返回
2018-01-13 00:27:10
