General :: A Script That Will Display Only The Last Login Of Each User With The Date And Year?

This is on an old machine that is running Solaris 7. I know that I can run the command script 'last' to get a list of who has logged in. When I do that I get a very long list of lines like:

username pts/4 100.32.11.123 Wed Dec 6 18:30 - 18:40 (00:09)

I see that the year is not posted. I have about 11 years worth of logins where users have logged in multiple times over several years.

So, here is what I need: I only need the date of the very last time a person logged in. I also need the year of that last login.

script that will do this? Something with output like

username1 pts/4 100.32.11.123 Wed Dec 6 2005 18:30 - 18:40 (00:09)
username2 pts/4 110.33.11.18 Tue Apr 20 2009 8:30 - 9:30 (01:00)
username3 pts/4 10.32.11.18 Mon Jun 12 2008 1:30 - 2:40 (01:10)
username4 pts/4 110.33.12.19 Sat Oct 10 2001 00:12 - 00:13 (00:01)
