Most of you must know the usage of 'ls'. Here I will show you some enhanced use of 'ls' with different switches where you can view the files and directories on the basis of their access and modification time along with different format of time and date.
To list all the directories on the basis of modification time
# ls -lt
drwxr-xr-x. 2 root root 4096 Oct 3 18:56 Desktop
drwxr-xr-x 4 root root 4096 Oct 3 14:16 rpmbuild
drwxr-xr-x. 2 root root 4096 Sep 8 16:00 Documents
drwxr-xr-x. 2 root root 4096 Sep 8 16:00 Music
drwxr-xr-x. 2 root root 4096 Sep 8 16:00 Pictures
drwxr-xr-x. 2 root root 4096 Sep 8 16:00 Public
drwxr-xr-x. 2 root root 4096 Sep 8 16:00 Templates
drwxr-xr-x. 2 root root 4096 Sep 8 16:00 Videos
drwxr-xr-x. 2 root root 4096 Sep 8 16:00 Downloads
To long list the files viewing the time of creation
# ls -l --time-style="+%d %m %Y"

The same can be used with different time switches
# ls -l --time-style=+%D
