Unix - File Creation Date
提问by helpermethod
For an assignment I need to determine the creation time of a random file. As far as I know, Unix does not store the creation time (in contrast to *-BSD). I think I've read somewhere that you should ask for the modification time instead but I don't know where and asking Google doesn't give me a non-ambigious answser either.
对于作业，我需要确定随机文件的创建时间。据我所知，Unix 不存储创建时间（与 *-BSD 相反）。我想我在某个地方读到过，你应该要求修改时间，但我不知道在哪里，问谷歌也不会给我一个明确的答案。
Any ideas?
有任何想法吗？

You cannot get the creation time of files in this context. That makes the assignment easy enough: it reasonably cannot be completed.
在这种情况下，您无法获得文件的创建时间。这使得分配足够容易：它合理地无法完成。
If someone is talking about creation time in Unix, they are confused. Modification time is completely different from creation time (obviously).
如果有人在谈论 Unix 中的创建时间，他们会感到困惑。修改时间与创建时间完全不同（显然）。
For the record, there are exactly three timestamps in Unix files: ctime, atime and mtime.
作为记录，Unix 文件中正好有三个时间戳：ctime、atime 和 mtime。
