What makes you think that it's not the time of the nginx box?  
Note well: it's in GMT as required by RFC 2616, not in your local 
timezone.

And no, you can't stop nginx from sending Date header as it's 
required per RFC 2616.  The only thing you may do is to pass 
to client original Date header as got in response from backend 
(via proxy_pass_header Date).

Directive proxy_set_header sets headers to be sent to backend 
server.  If you want to add headers to response you should use 
add_header directive.
