\title{(Title)}
\subtitle{( ABC......(new line) Timeperiod: 10.11.-12.11.12)}
\author{(Author)}

\maketitle

Answer 1

Just create your own coverpage, drop the \maketitle, or renew it to something like:

\renewcommand\maketitle{%
        \begin{center}
            \thispagestyle{empty}
            \textsc{\LARGE }\\[2cm]
            \textsc{\Huge The Title}\\[1cm]
            \textsf{\normalsize The Subtitle}\\[1cm]

            \textsc{\LARGE\Bla Bla Bla}\\[0.075cm]
            \textsf{\small and}\\[0.15cm]
            \textsf{\large\Bla Bla}\\[1.5cm]

            \textsf{\small by}\\[1.5cm]
            \textsc{\large Ya Di Ya Di Ya}\\[0.25cm]
            \textsc{\large 1st January 1999}\\[1.75cm]
            \includegraphics[width=0.3\textwidth]{logo.png}  %Insert Your Image Here.
        \end{center}
    }

Which Creates a Coverpage like the following, when you actually call the \maketitle command.
