扣丁学堂Python培训简述Python获取utc时间转化为本地时间的方法

本篇文章扣丁学堂Python培训小编给读者们分享一下Python获取utc时间转化为本地时间的方法，感兴趣的小伙伴就随小编来了解一下吧，希望对小伙伴们有帮助。

方法一：

import datetime
timenow = (datetime.datetime.utcnow() + datetime.timedelta(hours=8)) #将utc时间转化为本地时间
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) #将2017-12-21T04:57:42.000Z 字符串转化为时间
re = dateutil.parser.parse(re_time)
start_time =(st+datetime.timedelta(hours=8)) #将#将utc时间2017-12-21T04:57:42.000Z 转化为时间本地时间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))+"
"

python 从es中获取数据

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={
 "size":42,
 "query": {
 "term": {
 "itv_account": {
 "value": "38:FA:CA:D9:5F:2B"
 }
 }
 },
 "sort": [
 {
 "report_time": {
 "order": "desc"
 }
 }
 ],
 "_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))+"
"
 write_file.write(message)
write_file.close()

方法三：

UTC转化UTC

utc1 = 1406869066, utc2 = 1406869070 相差4, 也就是这两个时间相差4秒
