One thing to be aware of is:

The file's access Time,atime is changed when the file is read or executed, which is updated every time the file is opened.

The modified time,mtime of a file is changed when the file is written with changes to the contents of the file.

The file's create Time,ctime is changed as the content of the inode changes when writing to a file, changing owner, permission, or link settings .

As a result, changing the contents of a file changes mtime and CTime, but the CTime of the file may change when the mtime does not change, such as when the permissions change, but the contents of the file do not change.
