tikz-timing: How to change size of names of all signals

Question

I want the names of the signals to be smaller.

Questions:

1. How do I make only one smaller?
2. How do I preconfigure that all signals of all graphics generated in the document to have a smaller size for the signal names?

Here is a MWE:

\documentclass{article}
\usepackage{tikz-timing}
\begin{document}
This is a test graphic.\
\begin{tikztimingtable}
        clk & 21{C}; \\
        data  &  5L;2H;14L \\
\end{tikztimingtable}


Another graphic, but i want the size of all signal names to be smaller.\
\begin{tikztimingtable}
        clksmallersize  & 21{C}; \\
        data2  &  5L;2H;14L \\
\end{tikztimingtable}


\end{document}

Answer 1

Figured it out:

\documentclass{article}
\usepackage{tikz-timing}
% The following lines makes all signal names smaller in all document
%\tikzset{timing/name/.style={font=\sffamily\scriptsize}}
\begin{document}
This is a test graphic.\
\begin{tikztimingtable}
        clk & 21{C}; \\
        data  &  5L;2H;14L \\
\end{tikztimingtable}


Another graphic, with names of signals smaller.\
% adding this in brackets, makes the signals of the tikztimingtable smaller, only for that table.
    \begin{tikztimingtable}[timing/name/.style={font=\sffamily\scriptsize}]
            clk_smallersize    & 21{C}; \
            data_smallersize &  5L;2H;14L \
    \end{tikztimingtable}
\end{document}
