首先，戳记携带一个日期。

First, stamps carry a date.

youdao

生成戳记的日期(和时间)。

The date (and time) a stamp was minted.

youdao

当然，还需要校验哪个资源是您识别出来的那个资源(比如您的收件人地址之一)，那个戳记还没有被使用过，日期是当前日期。

Of course, it is also worth checking that the resource is one you recognize (like one of your recipient addresses), that the stamp was not spent before, and that the date is current.
