tex.month can't be overridden like tex.day and tex.year

tex.month can't be overridden like tex.day and tex.year

[Tristan Stenner]

Dear list,

in the following document I can set the date as seen by LuaTeX so the
date functions use a different date:

---
\starttext
\ctxlua{tex.year=1980; tex.month=1; tex.day=15}

% Taken from https://wiki.contextgarden.net/Command/date,
% outputs 15 may 1980
\date[m=1][day,~,{\monthshort\normalmonth},~,year]

% outputs January 15, 1980
\ctxlua{context.date{m=tex.month};}
\stoptext
---

This works for all parts of the date (even the weekday), except the
month. I've looked through the core-con.lua and found nothing that would
explain this (or what I'd need to change), as the tex.month is properly set.

Best regards
Tristan

\meaning\day   \par
\meaning\month \par
\meaning\year  \par

\meaning\normalday   \par
\meaning\normalmonth \par
\meaning\normalyear  \par


context (re)defines \month so you need to use the original meanings 
(\normal..)
