求翻译，多谢了

奇怪，明明写的是 b e t w e e n,为何老显示“ b广告een”,看看其它福友是不是也有这个情况。

There is one week difference on the Lot Number b广告een   the invoice and the actual goods, but we will still assume the warrenty during this time.

FYR.

或者你可以用 the date was one week ahead or later than来表示差一周。

倒签，提前签。

THANKS FOR YOUR HELP，可否问下anti-dated是什么意思？

The Lot Number on the invoice was anti-dated one week against the actual Lot Number,which we will still be responsible for
the warrenty.
