当我使用包时，我在今天安装的 TL 2016 下使用 lualatex 进行编译时出现错误datetime。此 MWE 在 TL 2015 下运行正常。如何解决此错误？看起来datetime包的 API 已更改。
\documentclass[11pt]{scrbook}%ext
\usepackage{luatex85} %needed else gets an error with lualatex in 2016
\usepackage[us,12hr]{datetime}
\begin{document}
\currenttime
\end{document}
错误是

在 TL 2016 中使用 pdflatex 编译成功，在 2015 中使用 lualatex 编译成功：
\documentclass[11pt]{scrbook}%ext
\usepackage[us,12hr]{datetime}
\begin{document}
\currenttime
\end{document}
没有错误：

更新：
在最新的 tlmgr 更新之后，luatex85.sty 2016/06/15 v1.4 pdftex aliases for luatex现在无需使用来\edef\pdfcreationdate {\pdffeedback creationdate}修复问题。因此，最终代码现在可以编译如下，错误也消失了：
\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}
但是首先需要运行来从 CTAN 中sudo /usr/local/texlive/2016/bin/x86_64-linux/tlmgr update --all选择luatex85刚刚更新的更新。
答案1
% !TeX program = lualatex
\documentclass[11pt]{scrbook}%ext
\usepackage{luatex85} %needed else gets an error with lualatex in 2016
\edef\pdfcreationdate {\pdffeedback creationdate}
