Richard it looks like the only option available with the software that I can
take is to remove the +1200 and just post the date/time of the BBS message
as it lands at the gateway without it. At least that's what I think will
happen. Let's see. I have removed the +1200 so this post and any other from
this side in the comings days will not have the +1200

I also wonder if when using +1200 (which is correct for New Zealand where the 
gateway is based) if I should have added GMT to the time stamp to avoid any
confusion? e.g. +1200 GMT

The actual formatting of the Date: header field looks to be correct to me.
as per RFC 1036
