Long ago I would have just used
$ rpm -qa
and possibly piped it through more. Looks like is still works.
dmckee's answer works perfectly well.
$ yum list installed
also works. No special privileges required.
rpm -qa --last >~/RPMS_by_Install_Date
this will also give you a list of when they were installed as well ... the file will be made in your home dir.
