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) 

结果如下:
