There is a good workaround for build automation:
构建自动化有一个很好的解决方法：
copy /b <Filename> +,,
I found this trick here: https://superuser.com/questions/292630/how-can-i-change-the-timestamp-on-a-file. The strange is that "copy /?" does not say about /b option.
我在这里找到了这个技巧：https: //superuser.com/questions/292630/how-can-i-change-the-timestamp-on-a-file。奇怪的是“复制/？” 没有说 /b 选项。
