Question: I'm trying to generate a clock similar to as in the question asked [here](https://tex.stackexchange.com/questions/49427/reproducing-an-analog-clock-similar-to-the-one-provided-by-the-ifsym-package)

But I want the face to be numbered. Is this possible with this package or any other?

Answer: 
A little variation of an example taken from the PGF documentation (Section **83
Repeating Things: The Foreach Statement**, page 912 for version 3.0):

```
\documentclass{article}
\usepackage{tikz}

\begin{document}

\begin{tikzpicture}[line cap=rect,line width=3pt]
\filldraw [fill=cyan] (0,0) circle [radius=2cm];
\foreach \angle [count=\xi] in {60,30,...,-270}
{
  \draw[line width=1pt] (\angle:1.8cm) -- (\angle:2cm);
  \node[font=\large] at (\angle:1.36cm) {\textsf{\xi}};
}
\foreach \angle in {0,90,180,270}
  \draw[line width=2pt] (\angle:1.6cm) -- (\angle:2cm);
\draw (0,0) -- (120:0.8cm);
\draw (0,0) -- (90:1cm);
\end{tikzpicture}

\end{document}

```

An perhaps one could define a command to control some attributes; below an example, allowing to specify the color, the radius and the font size for the numbers:

```
\documentclass{article}
\usepackage{tikz}
\usepackage{xparse}

\NewDocumentCommand{\Clock}{O{2cm}O{\large}O{cyan}}{%
\def\radius{#1}%
\begin{tikzpicture}[line cap=rect,line width=0.055*\radius]
\filldraw [fill=#3] (0,0) circle [radius=\radius];
\foreach \angle [count=\xi] in {60,30,...,-270}
{
  \draw[line width=1pt] (\angle:0.9*\radius) -- (\angle:\radius);
  \node[font=#2] at (\angle:0.68*\radius) {\textsf{\xi}};
}
\foreach \angle in {0,90,180,270}
  \draw[line width=0.04*\radius] (\angle:0.82*\radius) -- (\angle:\radius);
\draw (0,0) -- (120:0.4*\radius);
\draw (0,0) -- (90:0.5*\radius);
\end{tikzpicture}%
}

\begin{document}

\Clock\quad\Clock[1cm][\footnotesize][orange]

\end{document}

```

Bit off topic-answer, once I made a "mathematican clock" as a birthday present. The result was printed out, and I replaced the number plate of a real clock with it:

```
\documentclass[landscape,a3paper,extrafontsizes,12pt]{memoir}
\usepackage[a3paper,margin=0.2cm]{geometry} 
\usepackage{tikz}
\usepackage{amsmath}
\begin{document}
\begin{center}
\vspace*{\fill}

\begin{tikzpicture}
    \foreach \x in {0,30,...,360} {
        \draw [line width = 0.1cm] (\x:9cm) -- (\x:10.5cm);
    };
    \foreach \x in {0,6,...,360} {
        \draw [line width = 0.05cm] (\x:10cm) -- (\x:10.5cm);
    };
    \draw (0:0cm) circle [radius = 0.2cm];

    \node (1) at (60:7cm) {\Large $\boldsymbol{9^{9-9}}$};
    \node (2) at (30:7cm) {\Large $\boldsymbol{\dfrac{9+9}{9}}$};
    \node (3) at (0:7cm) {\Huge $\boldsymbol{\sqrt{\log_{9}{9^9}}}$};
    \node (4) at (-30:7cm) {\Large $\boldsymbol{\sqrt{9}+\log_{9}9}$};
    \node (5) at (-60:7cm) {\Large $\boldsymbol{\sqrt{9}!-\log_{9}9}$};
    \node (6) at (-90:7cm) {\Huge $\boldsymbol{9 - \dfrac{9}{\sqrt{9}}}$};
    \node (7) at (-120:7cm) {\Large $\boldsymbol{\sqrt{9}!+\dfrac{9}{9}}$};
    \node (8) at (-150:7cm) {\Large $\boldsymbol{9 - \dfrac{9}{9}}$};
    \node (9) at (-180:7cm) {\Huge $\boldsymbol{\sqrt[9]{9^9}}$};
    \node (10) at (-210:7cm) {\Large $\boldsymbol{9 + \log_{9}{9}}$};
    \node (11) at (-240:7cm) {\Large $\boldsymbol{\dfrac{99}{9}}$};
    \node (12) at (-270:7cm) {\Huge $\boldsymbol{9 + \dfrac{9}{\sqrt{9}}}$};
\end{tikzpicture}
\vspace*{\fill}
\end{center}
\end{document}

```

(this is an excerpt, the original had also numbers 0-59 on each of the minutes line)

There are no hands, as those were provided by the real clock
