Three times of Linux files (find for example):

Atime last access time, such as LS, more, but chmod, chown, LS, stat, etc. will not modify some time, use Ls-utl can be viewed in this chronological order;

CTime Last state modification time, such as chmod, Chown and other state time changes but the modification time will not change, using stat file can be viewed;

Mtime Last content modification time, such as VI after saving, change time changes, Atime and CTime also change accordingly.

Attention:

The creation time of a file is not recorded in Linux unless the file has not changed since it was created, and its creation time is the last time it was modified.

#ls-lt/home/admin # View in modified chronological order

#ls-lut/home/admin # View by Access time order

(If you want to reverse-order view, you need to add an option-R)
