Post dateline from bbcode plugin

[ctrlbrk]

Hi,

I need a fixed-in-time dateline time() that does not change when someone quotes a reply.

Example:
1) Bob writes a post today. BBcode works, and uses time() to generate a dateline.
2) John replies to Bob's post at a later date, and the BBcode needs to reference the fixed-in-time time() from the original post 1, but instead it generates a new dateline as of John's reply.

There is no $post[dateline] in the bbcode_create.

The goal is for the bbcode to generate a dateline based on the POST dateline, and not the current system time().

Any help greatly appreciated.
