Fecha junto al autor

Question

Creé mi propio formato de título usando titling. Preferiría que la fecha esté en la misma línea que el autor, separada por una coma. ¿Es eso posible?

\documentclass[a4paper,10pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[english]{babel}
\usepackage{geometry}
\geometry{
  left=3cm,
  right=3cm,
  top=2cm,
  bottom=4cm
}
\usepackage{titling}
\pretitle{\begin{center}\LARGE\scshape\bfseries}
\posttitle{\par\end{center}\vskip 0.5em}
\preauthor{\begin{center}\large\scshape\lineskip 0.5em\begin{tabular}[t]{c}}
\postauthor{\end{tabular}\par\end{center}}
\predate{\begin{center}\large\scshape}
\postdate{\par\end{center}\vskip 0.5em}
\title{Some title}
\author{Some author}

\begin{document}
\maketitle
\end{document}
