I'm just getting started with awk, but this seems to work:

ls -lt /var/lib/dpkg/info/*.list | sed 's/.*\(200[0-9]\)/\1/g' | 
   awk '$0 > "2007-03-01"' | awk -F"/" '{print $6}' | 
       awk -F"." '{print $1}' > list.txt

This produces a list of packages altered after 2007-03-01. You can
change that date around, or extend it to select a particular hour or
minute on that day to use as the cut-off. 

Note that I have no idea what you're doing, or how dpkg works, I just
wanted to see if I could figure out a solution to the immediate
problem with sed and awk!
