Access Time = last access to the data of the file system entity
Modify Time = last modification time in milliseconds. 
				For example, the last change to file’s content.
Change Time = last time the file’s inode was changed in milliseconds. 
				Also changes when you change file’s ownership or access permissions.
Create Time = file was first created
