[Typo3] Content Header Date formatting

[Marlies C]

I was checking out the date field in the Content Header, but it does some 
strange things:

1. It is now 3:01pm March 7/05, but it show March 8/05
2. How can I change the display format. It shows 8/3/05, but I want it to 
show Monday, March 7/05.

For point 2 I have found that I have to somehow alter the something for 
lib.stdheader:
   lib.stdheader.field = tstamp
   lib.stdheader.date =

Ok, my questions are how to I create the proper typoscript to get the output 
I want and how can I get the proper day to show up not a day in the future.

Thanks
