\frametitle{Introduction}
\initclock % This must be used one time to initialize the clock
We are putting here a clock with the macro \quad
\structure{\texttt{$\backslash$tdclock}}:
\bigskip
\tdclock
\bigskip
Before that, the macro \quad \structure{\texttt{$\backslash$initclock}}
\quad must have been used (only one time !).
\end{frame}
% This is an example of inserting
% the clock at the place reserved to the date, the foot line in the
% case of Madrid theme.
%
\date{\tddate\ \ \tdtime}
\begin{frame}
Here we have inserted the clock at the place reserved to the date, the foot line in the case of Madrid theme.
\medskip
To do that, we have redefined the date contents with the order
\medskip
\centerline{\structure{\texttt{$\backslash$date\{$\backslash$tddate$\backslash$ $\backslash$ $\backslash$tdtime\}}} }
\medskip
Note that color and font size are adjusted according to the theme.
\medskip
Look at the foot!, the clock must be running.
\end{frame}
\begin{frame}
Next, we have inserted a button to toggle between clock and stopwatch,
and a button to reset the stopwatch to zero.
\medskip
\toggleclock{\beamerbutton{toggle}}
\tdtime
\resetcrono{\beamerbutton{reset}}
\medskip
Click at the left button, see what happens (you must wait 10 seconds),
then click at the right button and see the result.
Finally, click at the left button again to recover the current time
\bigskip
To do that, we have used
\medskip
\structure{
\texttt{$\backslash$toggleclock\{$\backslash$beamerbutton\{toggle\}\}} \\%
\texttt{$\backslash$tdtime} \\
\texttt{$\backslash$resetcrono\{$\backslash$beamerbutton\{reset\}\}}
}
\end{frame}
%
% Here we change the colors and size of the clock
\begin{frame}
Here we change the color and size of the clock with
standard \LaTeX commands.
\structure{\texttt{$\backslash$textcolor\{blue\}\{$\backslash$Large $\backslash$tdhours.$\backslash$tdminutes\}\}}}: %
\textcolor{green}{\Large \tdhours.\tdminutes}
\bigskip
Here a huge yellow clock showing only hours and minutes, inside a red box
\structure{$\backslash$hhmm $\backslash$factorclockfont\{6.0\} $\backslash$tdtime}
