Location of, or command to get installed date and time of a package.

[Ray Parrish]

Hello,

Is there a quick one line command that will return the installed date, 
and time of a software package in Linux, or Ubuntu more specifically?

Alternatively, is that data in a file somewhere in the file system? I'm 
sure it is, as Synaptic Package Manager has the data to look at, I just 
do not know where it stores the data.

I can parse the file myself, if I can discover where it resides.

Thanks for any help you can be.

Later, Ray Parrish
