Comment 20 for bug 194496

Clean install of Ubuntu 8.04 - fully updated as of May 16, 2008. I can reproduce the problem by the following:

Boot & reset the bios clock to 00:00:00 12/31/1987, bring up Ubuntu without a
network connection, Ubuntu login comes up with the bios time setting (31 Dec
1987), as expected. Enter username & password & Heron splash screen comes up. However, before it completes the desktop, it provides a popup telling me:

====
The computer clock appears to be wrong
The session might encounter issues if the computer clock
is not properly configured. Please consider adjusting it.
Current date is 12/31/1987
 Ignore Adjust the Clock
====

But then of course, I attempt to authenticate in order to adjust the clock and receive "Could not authenticate" , so I can't adjust it from the popup & can't get past the splash screen. Drop to a terminal (C-A-F1), connect to the network, reinit networking (sudo /etc/init.d/networking restart), Ubuntu goes out and gets the correct time. Switch back to gdm (C-A-F7) and the Ubuntu desktop completes without any further intervention from me.

I also have difficulties on this laptop authenticating using update-manager. The update manager will hang at "Update" and does not make it to the authentication screen. I end up having to kill UA and updating from the terminal (sudo apt-get update/upgrade). That problem also sometimes occurs on my other laptop & I wonder if it is memory related; both only have 128MB of RAM.

Reproducible: Always
policykit-gnome is installed - version 0.7-2ubuntu1
gnome-system-tools is installed - version 2.22.0-ubuntu9
Kernel - 2.6.24-16-generic

Let me know if I can provide any additional information from the logs to help.
