It's the problem.
I don't know why, but if the ntpd service is active and, in the boot 
process the network is unavailable you'll suffer this lack of time.

Making a definitive test is simple: deactive the ntpd service, take off 
the wireless NIC and reboot the system. If the next boot has the 
"normal" speed, you already know what is happens.

I wait you comments about.
