Bad start date in offline recurring creation : 1969-12-31

In my testing environment, when i create a new offline recurring contribution, i get a wrong start date in the civicrm_contribution_recur table : 1969-12-31 19:00:00
It's seems that the date is containing the time which cause problem in CRM/Contribution/Form/Contribution/Confirm.php :
<pre>
[receive_date] = 20111202113100
[receive_date_time] = 11:31
</pre>

I can't test it in the demo site because i need access to the database to verify the recurring contribution.

The patch attached resolve the problem but not sure if it's the best thing to do.
It may be better to check why there is time in receive_date in the first place.
