[luatex] Missing current creation date in doc of pdf.getcreationdate()

[Yukai Chou]

Hi all,

In the LuaTeX Reference Manual (v1.18), sec. 14.1.6 getcreationdate
(p. 286), the doc of pdf.getcreationdate() reads

    This function returns a string with the date in the format that
ends up in the pdf file, in this case  it’s: .

Notice the creation date of the manual itself is expected but missing.

The corresponding source are in luatex-backend.tex [1] but
unfortunately my ConTeXt knowledge is not enough to find a resolution
myself.

    This function returns a string with the date in the format that
ends up in the
    \PDF\ file, in this case it's: {\tttf \cldcontext{pdf.getcreationdate()}}.
