I see. So, maybe use or copy the date check from latex.ltx:
\def\@ifpackagelater{\@ifl@ter\@pkgextension}
\def\@ifclasslater{\@ifl@ter\@clsextension}
\@onlypreamble\@ifpackagelater
\@onlypreamble\@ifclasslater
\def\@ifl@ter#1#2{%
\expandafter\@ifl@t@r
\csname ver@#2.#1\endcsname}
\@onlypreamble\@ifl@ter
\def\@ifl@t@r#1#2{%
\ifnum\expandafter\@parse@version#1//00\@nil<%
\expandafter\@parse@version#2//00\@nil
\expandafter\@secondoftwo
\else
\expandafter\@firstoftwo
\fi}
\@onlypreamble\@ifl@t@r
