python 获取utc时间转化为本地时间的方法
方法一：
importdatetime
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：
importdatetime importdateutil.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2017-12-2112:57:42+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从es中获取数据
importos
importdatetime
fromelasticsearchimportElasticsearch
importdateutil.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"]
}
)
forhitinrs['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转化UTC
utc1=1406869066,utc2=1406869070相差4,也就是这两个时间相差4秒
