Comment 1 for bug 507021

Even when you log in graphically, the timestamp is still recorded in /var/log/wtmp, and the "last" command still works. Still, you are right in that it would be a good security feature to somehow present this to the user on login.

gdm was completely rewritten to work with xsplash in karmic, and it isn't as feature rich as it once was. I think the priority is to get the whole login stack up to feature parity with what was there before the transfer to the new gdm first, before implementing something new, but this is still a good idea for the future.
