ID: 137 🔗 Closed (Fixed) datetime2 1.5.3 Enrico Gregorio 2019-10-19 18:32:13 Use of \nr as a scratch macro conflicts with other packages

## Report

The datetime2 package uses \nr as a scratch macro for \define@choicekey{datetime2.sty}{useregional}

This conflicts with nccmath, that has a macro with that name.

It's true that the examples in xkeyval use \nr for the purpose, but it can be anything. Also \val can be anything.

It would be better to use \DTM@val and \DTM@nr.

### MWE

\documentclass{article}

\usepackage[useregional]{datetime2}
\usepackage{nccmath}

\begin{document}
\end{document}


## Evaluation

Fixed in version 1.5.4 (2019-10-21).
