Ok, i've done another test (at the moment i could reproduce it in
virtualbox):

I've started the installation on 18:01 localtime (here CET).

After creating and formatting the disk i have on sda3(=/):
,----[ dumpe2fs -h /dev/sda3 ]

Then i go over configure system, also set the Timezone to Europe/Berlin
but leave the HARDWARECLOCK to localtime.
Doing this current time in virtual machine is:
Sat Mar 29 18:42:23 CET 2008
(only timezone gets changed, not the time itself)

And here i think it "happend":
,----[ dumpe2fs -h /dev/sda3 ]

| Maximum mount count:      30

sda3 is still mounted, but the creation time is in the future. The same
what fsck found fault with on the next(first) boot.

I think the error is to change timezone during install but leave the
time itself unchanged. Or something like that, i'm not sure ;-)
But i think to ask the user before install:
What is your clock set (UTC/localtime)
and then *set* the clock (maybe also hwclock) before mkfs could solve
this creation times conflicts.
