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

运行结果

1640869590.0347595
1640869590
1640869590035

1640869590035

2.将日期转为秒级时间戳

dt = '2021-12-30 21:00:00'
ts = int(time.mktime(time.strptime(dt, "%Y-%m-%d %H:%M:%S")))
print(ts)

运行结果

1640869200

3.将秒级时间戳转为日期

ts = 1640869200
dt = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(ts))
print(dt)

运行结果

2021-12-30 21:00:00
