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, datenow.month, 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, nextTime.month, 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]
