Package Install Date

[Joel Breazeale]

Andrey,

My goal is to build a list of all the installed packages in
chronological order.  With such a list I can see which package were
installed beyond the initial set.  The reason for this is to be able
to tell a colleague what to install to get their Cygwin configured
like mine so they can use tools I've created.

I was hoping a package install date/time would be provided by the
package management system.  Absent an official package install
date/time I'll take whatever I can scrounge up!  A stat of <package>
in /etc/setup/<package>.lst.gz gives me a "Birth" date/time which is
sufficient for my purposes.  For example:

$ pkginstalldate 2>/dev/null | sort

The above helps me to remember I installed m4, vim and unzip beyond my
initial setup.

[I use /dev/null because of libpopt0 as mentioned in earlier
discussion.  I haven't quite gotten to the point where I feel
comfortable ignoring the error generated for it.]
