python之常用的时间格式转换

记得导入需要的包例如：

import datetime 
import time

1.utc时间转化为当地时间(cst时间)

def utc2local(utc_date):
    now_stamp = time.time()
    local_time = datetime.datetime.fromtimestamp(now_stamp)
    utc_time = datetime.datetime.utcfromtimestamp(now_stamp)
    offset = local_time - utc_time
    res_time = utc_date + offset
    return res_time

2.当地时间转化为utc时间

def local2utc(local_date):
    now_stamp = time.time()
    local_time = datetime.dat
