(TeX-код!)
Я определил TeX-макрос для сравнения значений даты и времени. Все работает хорошо, пока я не вставляю \the\day, чтобы вызвать его текущее значение. Может кто-нибудь представить, почему это работает со всеми функциями даты и времени, кроме \the\day?
%transformations of \time
\newcount\hour %
\newcount\hours %
\newcount\minutes %
\hour=\time \divide\hour by 60
\minutes=\time
\hours=\hour \multiply\hours by 60
\advance \minutes by -\hours
%end transformations of \time

Here, the day is displayed: {\bf \the\day}
\vskip1\baselineskip
Below, it works without calling the day by function
From Date: \fromcaldate[\the\year-\the\month-11 \the\hour:\the\minutes]
To Date: \tocaldate[2012-11-05 04:16]
Res Date: \rescaldatetime
\vskip1\baselineskip
Below, it does not work with calling the day by function (outcommented)
%Fromdate: \fromcaldate[\the\year-\the\month-\the\day 13:00]
%Fromdate: \fromcaldate[\the\year-\the\month-\the\day \the\hour:\the\minutes]
%Todate: \tocaldate[\the\year-\the\month-\the\day \the\hour:\the\minutes]
%Resdate: \rescaldatetime

У вас есть
\def\tocaldate[#1-#2-#3 #4:#5]{%
поэтому после должен быть пробел#3
Fromdate: \fromcaldate[\the\year-\the\month-\the\day 13:00]
в приведенном выше примере пробел отсутствует, 13поскольку пространство в файле поглощается при токенизации \day.
Использовать
Fromdate: \fromcaldate[\the\year-\the\month-{\the\day} 13:00]
