Put this into /etc/update-motd/:

---code
#!/bin/sh
printf "\n%s\n" "The current date:"
/bin/date
printf "\n"
---code

fresh 10.04 or 12.04: The logon time is displayed.
After upgrade from 10.04 to 12.04: The time the machine was rebooted
last is displayed.

pam_motd ist active:
helmut at mail:~$ sudo grep -ir pam_motd /etc/
/etc/pam.d/login:session    optional   pam_motd.so
/etc/pam.d/sshd:session    optional     pam_motd.so # [1]
helmut at mail:~$

Clear? :)
