Description redhat 2000-01-17 08:38:14 EST

The class file /usr/share/texmf/tex/latex/dinbrief/dinbrief.cls
(tetex-latex-0.9-6.i386.rpm) calculates a date in the form DD.MM.YY.
Since 1.1.2000 the YY is shown as 100, because it subtracts 1900
from the current year instead dividing it modulo 100.

Comment 1 Jeff Johnson 2000-01-17 10:29:59 EST

This problem is still preset in tetex-1.0.6:

\def\today{\number\day.\space\ifcase\month\or
  Januar\or Februar\or M\"arz\or April\or Mai\or Juni\or
  Juli\or August\or September\or Oktober\or November\or Dezember\fi
  \space\number\year}
\newcount\yearcnt
\yearcnt=\year
\advance\yearcnt-\number1900
\def\@znumber#1{\ifnum\number#1<10 0\number#1\else\number#1\fi}
\def\ntoday{\@znumber{\number\day}.%
            \@znumber{\number\month}.%
            \@znumber{\the\yearcnt}}
\def\@ntoday{\ntoday}

Comment 2 Trond Eivind Glomsrxd 2000-12-01 17:56:23 EST

It is fixed in the one shipping with Red Hat Linux 7 (possibly earlier, but at
least that one) - no mention of 1900 at all.
