• #!/usr/bin/python

• import time,datetime
  
• Atime=time.time() ##获取本地时间戳
  
• print Atime
  
• print time.strftime('%Y-%m-%d %H:%M:%S',time.gmtime(Atime)) ##将时间戳转换成2013-01-07 08:21:31
  
• Nowtime=time.strftime('%Y-%m-%d %H:%M:%S',time.gmtime(Atime))
  
• print time.mktime(time.strptime(Nowtime,"%Y-%m-%d %H:%M:%S")) ##将2013-01-07 08:21:31格式转换成时间戳

• print "++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++"
  
• print time.ctime() #格式如:Mon Jan 07 15:20:16 2013
  
• print time.localtime() #格式如:time.struct_time(tm_year=2013, tm_mon=1, tm_mday=7, tm_hour=15, tm_min=20, tm_sec=16, tm_wday=0, tm_yday=7, tm_isdst=0)
  
• print time.strftime("%Y-%m-%d %H:%M:%S",time.localtime()) #转换成:2013-01-07 15:20:16
  
• print time.strftime("%a %b %d %H:%M:%S %Y",time.localtime())#转换成:Mon Jan 07 15:20:16 2013
  
• a=time.ctime()
  
• b=time.strftime("%Y-%m-%d %H:%M:%S",time.localtime())
  
• print time.mktime(time.strptime(a,"%a %b %d %H:%M:%S %Y")) #将Mon Jan 07 15:20:16 2013这种格式转换成时间戳
  
• print time.mktime(time.strptime(b,"%Y-%m-%d %H:%M:%S")) #将2013-01-07 15:20:16这种格式转换成时间戳
  
• 
  
• print "+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++"
  
• print datetime.datetime.now() #获取现在时间精确到微秒
  
• Atime=datetime.datetime.now()
  
• Btime=datetime.datetime.now().microsecond/1000    #microsecond是微秒需要除以1000才能取出毫秒数
  
• Ctime=time.strftime("%Y-%m-%d %H:%M:%S",time.localtime())
  
• print str(Ctime)+str(Btime)
