Thank you for the explanation, I really appreciate that and I'm happy to
learn new possibilities in org.  At first I thought it just a regression
that I had additionally to put in a macro but on the other hand it is
much more precise for my needs then

#+DATE %Y-%m-%d

which gave me in 7.xx only the current time.  So far so good.

#+DATE: {{{modification-time(%Y-%m-%d)}}}

is working when I'm exporting individual files but now when I'm trying
to publish I'm getting:

Generating tree-style sitemap for Die D=C3=BCnenhof-Seite [15 times]
byte-code: Bad timestamp `((macro (:key modification-time :value {{{modific=
ation-time(%Y-%m-%d)}}} :args (%Y-%m-%d) :begin 1 :end 34 :post-blank 0 :pa=
rent #0)))'
Error was: (stringp ((macro (:key modification-time :value {{{modification-=
time(%Y-%m-%d)}}} :args (%Y-%m-%d) :begin 1 :end 34 :post-blank 0 :parent #=
1))))

Seemingly this macro wreaks havoc with the automatic sitemap
generation...

Thanks

        Dieter
