在實際中遇到一個時間處理問題，需要將 Sep 06, 2014 19:30 （UTC 時間） 和 當前時間比較早晚，知道 此 2014-09-06 19:30 格式時間的運算。因此，在處理時，就想
先將sep 格式時間轉化成 後面一個格式的時間樣子，沒有找到相關函式，於是自己簡單的寫了個程式，僅記於此，以備查詢
程式碼如下：
# -*- coding: utf-8 -*-
from datetime import date
from datetime import datetime
from datetime import timedelta
# # #如果是返回當前時間，可以簡單的寫成
# # time.localtime()
# # #這個返回UTC時間
# # time.gmtime()
# lt = time.localtime()
# tm = time.gmtime()
# ft = time.strftime('%Y-%m-%d %H-%M',lt)
# ft2 = time.strftime('%Y-%m-%d %H:%M',tm)
# print ft, ft2
# print '--------------------------------------------------------'
# now = datetime.datetime.now()
# now = now.replace(day = 1)
# print now
# print now.time()
#
# mytime = ['2014-09-06 20:19']
# #mytime2 = '2014-10-09 14:32'
# str = "".join(mytime)
# print str
# retime = datetime.strptime(str,'%Y-%m-%d %H:%M')
# print retime
# retime = retime +timedelta(hours = 8)
# print retime
#
# tdtime = datetime.now()
# print tdtime
# if retime <= tdtime - timedelta(days = 7):
# print "too early"
#
# #Sep 06, 2014 19:30

def time_format(timestr):

#print timestr

#print timelist
