A comparison of Linux3 time and Inode

Access time (atime) is changed when you read a file or execute a file.

Modified time (mtime) is changed when writing a file that changes with the contents of the file.

Create time (CTime) is the two changes that are changed with the inode content when writing to a file, changing owner, permission, or link settings.

The inode is a kind of data structure in UNIX system, which is essentially a structure, which is generated when the file system is created and has a limited number, which is used to store the basic information of archives and directories, including time information, document name, owning group and so on.

Mtime, Atime is modified, the inode must be modified, then ctime followed by modification.
