python UNIX_TIMESTAMP时间处理方法分析

本文实例讲述了python UNIX_TIMESTAMP时间处理方法。分享给大家供大家参考，具体如下：

from datetime import datetime
import time
int(time.mktime(rm.start_time.timetuple()))
 datetime.fromtimestamp(time.time())
rf.start_time + timedelta(0,math.ceil(diff.total_seconds()/(3600*rf.period))*3600*rf.period)

获取按月或者小时偏移时间

def getlastday(datetimeobj):
 year= datetimeobj.year
 month = datetimeobj.month + 1
 if month>12:
  year = year + 1
  month=1
 return datetime(year,month,1) - timedelta(1)
def getSendTime(period,start_time):
 datenow = datetime.now()
 nextTime = preTime = start_time
 if period > 0 and period < 1000:
  diff = datetime.now() - start_time
  nextTime = start_time + timedelta(0,math.ceil(diff.total_seconds()/(3600*period))*3600*period)
  preTime = start_time + timedelta(0,math.floor(diff.total_seconds()/(3600*period))*3600*period)
 if period == 1001:
  if datenow.day>start_time.day:
   preTime = datetime(datenow.year,datenow.month,start_time.day)
   nextTime = getlastday(getlastday(datenow)+timedelta(1))
   if nextTime.day > start_time.day:
    nextTime = datetime(nextTime.year,nextTime.month,start_time.day)
  else:
   preTime = getlastday(datetime(datenow.year,1) - timedelta(1))
   if preTime.day > start_time.day:
    preTime = datetime(preTime.year,preTime.month,start_time.day)
   nextTime = getlastday(datenow)
   if nextTime.day > start_time.day:
    nextTime = datetime(nextTime.year,start_time.day)
 return preTime,nextTime

排序

reportMetaPeriodInfo.sort(lambda p1,p2:cmp(p1['k'],p2['k']))

获取ip

import socket
s = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
  s.connect(('8.8.8.8',0))
  localIP=s.getsockname()[0]
