Where do I modify the "heading" used for the extra display items db_show[3] and db_show[4]...

Right now it says Date: (db info) - Time: (db info)

I want to modify it so that these extra parameters show like:

Heading for db_show[3]: (db_show[3])

ie so that it says something other than "Date" because the "date" is not the info I am trying to show here

Thanks
