In amsart, how do you include two dates (in the footnotes)?

Specifically, another one (displayed after the label Last update) in addition to the default one (\date), with the same options.

\documentclass[10pt]{amsart}
\usepackage[foot]{amsaddr}

\begin{document}
\title[Short Title]{Long Title}
\author[Surname]{Name Surname}
\address{University}
\email{email@email.com}
\date{14/09/2015}

\maketitle

\end{document}

  • Please give us a minimal document which we can compile. We do not want to set up a whole example for you just in order to add a fixed date. – LaRiFaRi Sep 14 '15 at 8:50
  • @LaRiFaRi : Upon a change of mind, I revised the question. I hope it is not a problem. – user87695 Sep 14 '15 at 9:04
  • Would this trick be enough for you? \date{September 14, 2015; \textit{Last updated}:~\today}. This needs no further patching of your class and the package amsaddr – LaRiFaRi Sep 14 '15 at 9:28
  • @LaRiFaRi Actually, yes, thank you: it would serve my purpose well. However, I'd like to learn how to set up a second date too (it's always useful to learn something new after all). – user87695 Sep 14 '15 at 9:30

You can add some infrastructure to amsart.cls:

\documentclass[10pt]{amsart}
\usepackage[foot]{amsaddr}

\makeatletter
\def\@setdate{%
  \datename\ \@date
  \ifx\last@update\@empty\else
    .\ \lastupdatename\ \last@update
  \fi
  \@addpunct.%
}
\def\lastupdatename{\textit{Last Update}:}
\def\lastupdate#1{\gdef\last@update{#1}}
\let\last@update\@empty
\makeatother


\begin{document}
\title[Short Title]{Long Title}
\author[Surname]{Name Surname}
\address{University}
\email{email@email.com}
\date{14/09/2015}
\lastupdate{\today}

\maketitle

\end{document}

  • Is it possible to add \vspace{1mm} between the email address and the two dates? (I tried, but it doesn't seem to work.) – user87695 Sep 14 '15 at 10:13
  • @Ryo Yes, but you need to modify the redefinition of \@maketitle made by amsaddr.sty. I see no improvement, though. Of course, the journal which you submit the paper to will reject these changes anyway. – egreg Sep 14 '15 at 10:15
  • I see. And how do you do that? – user87695 Sep 14 '15 at 10:16
  • @Ryo Ask a new question; but this is quite complicated, because other bits of information could follow the email address and the date could not be set. And, as I said, I see no real improvement in the output. – egreg Sep 14 '15 at 10:18
  • By the way, could you have a look at this other (somewhat related) issue? – user87695 Sep 14 '15 at 10:27
