The following might be helpful, I don't know if there's an easier solution.
Use the following command to learn about the installation date of kdevelop3:
Code:
barnabas:~ # rpm --query --info kdevelop3
Name : kdevelop3 Relocations: (not relocatable)
Version : 3.3.4 Vendor: openSUSE Build Service
Release : 13.4 Build Date: Thu Sep 14 15:10:12 2006
Install Date: Sun Sep 17 15:14:27 2006 Build Host: build07
[...]
So we've got "Sun Sep 17 15:15:19 CEST 2006" here. Then the following command will return a list of all packages that have been installed on Sun Sep 17 2006:
Code:
rpm --query --queryformat "%{NAME} %{INSTALLTIME}\n" --all | (while read NAME TIME; do echo $NAME $(date --date=@$TIME); done) | grep "Sep 17 .* 2006"
