The 49,000 years of creation was last promoted in the literature as late as 1987 I believe.
I don't think today they specify an allotted time for each day. They just say that each period was a long period of time.
When they have got more specific, like in the publication 'The Origin Of Life', they have used the estimates of science, although they don't specify they believe such estimation as true.
However you look at it, be it six literal days or six long periods of time, none of it stacks up to what science has discovered. The bible's account is incorrect, plain and simple.
