关于USC滴财产证明

前几天收到ad后发邮件问关于财产证明滴东东，回复如下：
1.) Your financial statement may show either RMB or USD, or both. We do not require your funds to be frozen. Your statement must be dated within a year of your intended start date.

2.) There is no immediate deadline to submit your financial documents. Please try to submit them at your earliest convenience.

第1）的最后一句话不懂啊！！！求指点

Your statement must be dated within a year of your intended start date.
如果你计划2015年9月1号上学，你的存款证明应该是2014/9/1到2015/9/1之间开出的

你方便的情况下越早越好了

楼上的回答也是醉了＝ ＝
就是字面的意思
