请参阅我的示例代码：
import time
start_time_string = "2013-05-24 17:51:06"
end_time_string = "2013-05-24 17:59:33"
start_time_stamp = time.mktime(time.strptime(start_time_string, "%Y-%m-%d %H:%M:%S"))
start_time_struct = time.localtime(start_time_stamp)
end_time_stamp = time.mktime(time.strptime(end_time_string, "%Y-%m-%d %H:%M:%S"))
end_time_struct = time.localtime(end_time_stamp)
# what's the next step to get duration time, like x minute?
我看过https://docs.python.org/2/library/time.html，但找不到方法。
谢谢！
