python 獲取utc時間轉化為本地時間

python 獲取utc時間轉化為本地時間

方法一：

import datetime

timenow = (datetime.datetime.utcnow() + datetime.timedelta(hours=8)) #將utc時間轉化為本地時間

timetext = timenow.strftime('%y%m%d')

方法二：

import datetime

import  dateutil.parser

st_time = hit['_source']['start_time']

re_time = hit['_source']['report_time']

igmp_delay = hit['_source']['igmp_delay']

live_delay = hit['_source']['live_delay']

st = dateutil.parser.parse(st_time)  #將2017-12-21t04:57:42.000z 字串轉化為時間

re = dateutil.parser.parse(re_time)

start_time =(st+datetime.timedelta(hours=8))  #將#將utc時間2017-12-21t04:57:42.000z 轉化為時間本地時間2017-12-21 12:57:42+00:00

report_time = (re+datetime.timedelta(hours=8))

message = str(start_time)[0:19]+","+str(report_time)[0:19]+","+str(int(igmp_delay))+","+str(int(live_delay))+"\n"

python 從es中獲取資料

import os

import datetime

from elasticsearch import  elasticsearch

import  dateutil.parser

es = elasticsearch(hosts="127.0.0.1",timeout=10000)

write_file=open('c:\\users\\administrator\\desktop\\gather-005-201712210.csv',"a+",encoding="utf-8")

rs = es.search(

index = "gather-005-20171221",

body=}},

"sort": [}],

"_source": ["start_time","report_time","igmp_delay","live_delay"]})

for hit in rs['hits']['hits']:

st_time = hit['_source']['start_time']

re_time = hit['_source']['report_time']

igmp_delay = hit['_source']['igmp_delay']

live_delay = hit['_source']['live_delay']

st = dateutil.parser.parse(st_time)

re = dateutil.parser.parse(re_time)

start_time =(st+datetime.timedelta(hours=8))

report_time = (re+datetime.timedelta(hours=8))

message = str(start_time)[0:19]+","+str(report_time)[0:19]+","+str(int(igmp_delay))+","+str(int(live_delay))+"\n"

write_file.write(message)

write_file.close()

方法三：

utc  轉化utc

utc1 = 1406869066, utc2 =  1406869070  相差4, 也就是這兩個時間相差4秒
