This is a common misconception; I've seen it for the last 10 years.

The UNIX filesystems record the time the file was last read, the time
the file was last written or created, and the last time the inode was
changed or the file was written. (UNIX 7th edition doc).
Or, according to POSIX, time of last access, time of last data modification,
and time of last file status changes.

In other words, creation time is not preserved after the file is opened
the second time.
