Linux How to check all the installed packages by date time?

In Debian derived linux there is one folder "/var/lib/dpkg/info" this folder contains all the information about all installed packages in your system.

By issueing the following command we get them by date time.

$ls -l /var/lib/dpkg/info

output is in alphabatical order. To reverse the out put (i.e z to a)

$ls -l /var/lib/dpkg/info | tac :)
