"Three fields in the inode structure contain the last access, change, and modification times: atime, ctime, and mtime. The atime field is updated each time the pointer to the file's data blocks is followed and the file's data is read. The mtime field is updated each time the file's data changes. The ctime field is updated each time the file's inode changes. The ctime is not creation time; there is no way under standard Unix to find a file's creation time."

Have you done a Google search?

As per Pixellany, its in google. That quote is actually from my Perl Cookbook. Its a common misconception about ctime.
