Recently I ran into a problem on my machine at home.  I had

What I need is a way to query all installed packages by their
install date.  I couldn't find any existing tools like
dselect, synaptic, or aptitude that would let me do this.  The
only thing I can think of is writing a perl script using the
output of `dpkg -s` on every installed package.  This would
take a long time for sure.  I didn't see any packages or docs
on functions used inside dpkg.  Is there another way to do
this b/c I don't want to re-invent the wheel.


hmm.

i see installed-size, status: installed... but no
installed-time...

if there were one, hobbling a perl script to parse it would be
reasonably trivial (except for parsing date strings, and there's
libraries to help with that).
Yeah I noticed that, too. I think this may be difficult to tackle. The only thing I could think of would be to write a script in /etc/apt/apt.conf similar to localepurge that just writes to a logfile every time you install a package.
