datetime package does not work with lualatex in TL 2016

Question

I am getting error compiling using lualatex under TL 2016 installed today when I use package datetime. This MWE works ok under TL 2015. How to resolve this error? It looks like the API to the datetime package has changed.

\documentclass[11pt]{scrbook}%ext
\usepackage{luatex85} %needed else gets an error with lualatex in 2016
\usepackage[us,12hr]{datetime}
\begin{document}
\currenttime
\end{document}

error is

Compiles ok with pdflatex in TL 2016 and compiles OK with lualatex in 2015:

\documentclass[11pt]{scrbook}%ext
\usepackage[us,12hr]{datetime}
\begin{document}
\currenttime
\end{document}

update:

After latest tlmgr update, luatex85.sty 2016/06/15 v1.4 pdftex aliases for luatex now works without having to use the \edef\pdfcreationdate {\pdffeedback creationdate} to fix things. So the final code now compile as below and the error went away:

\documentclass[11pt]{scrbook}%ext
\usepackage{luatex85} %needed else gets an error with lualatex in 2016
\usepackage[us,12hr]{datetime}
\listfiles
\begin{document}
\currenttime
\end{document}

But one needs to run sudo /usr/local/texlive/2016/bin/x86_64-linux/tlmgr update --all first to pick the updated luatex85 just updated now from CTAN.

% !TeX program = lualatex
