我感觉选E,to be 应该表示将来.请高手指点

C吧。这应该是一个固定搭配的问题，查了一下电子词典，date sth at some time 这样的话，E应该对吧，date to be 总觉得怪怪的.....

应该选E吧。我查了一下字典，没有date to be + time的用法,只有sth. be动词 dated to + 时间.C应该把have been dated to be 中的be去掉才对。

网上找了这样一句，不知对大家有启发否？

and what more surprizes me is, that it is dated at the very time when you would have me imagine you was under such concern on my account.
