Show clock in beamer presentation

Question

Is there any possibility to add a clock to be shown in each slide using beamer?

What kind of clock? Just any clock? The current time? Should it tick on a current slide? — Werner, Nov 18 '13 at 20:03
@phdstudent: Why not just use a stopwatch? The PDF file format is fixed, so if you want a dynamic counter to keep track of it, it has to use Java (supported by certain PDF viewers). Also, what good would a counter be for the viewer? Instead you can use a beamer progress bar. It's far more useful to the viewer that a clock. — Werner, Nov 18 '13 at 20:07

There are also some nice visual counters Visual counter for LaTeX? — Claudio Fiandrino, Nov 18 '13 at 20:13
would the 'tdclock' theme do what you want?http://www.ctan.org/tex-archive/macros/latex/contrib/tdclock — prettygully, Nov 18 '13 at 21:37
What about an always on top external clock application? Is that a total abomination? :) I think it IS the easiest and most elegant way... — masu, Nov 18 '13 at 22:25
You can use impressive. It has a clock with t shortcut. http://impressive.sourceforge.net/ — , Nov 18 '13 at 23:07

impressive offers, among lot of other features, a clock that shows the time elapsed on the right upper corner. The clock is visible to audience also. The clock can be made visible/invisible by the short cut key t . For details of other features and short cuts refer to the impressive documentation (impressive.html, found in the same folder).

Ok. That is cool! But how to use it? Could you give more details? The informations in the website are poor. – lucenalex Dec 05 '22 at 15:06

There is a package called tdclock. However, to make it useable it must be patched. See https://tex.stackexchange.com/a/148464

\documentclass{beamer}
\usepackage[font=Helv,timeinterval=60]{tdclock}

\setbeamertemplate{headline}{\initclock\tiny{\tdyear-\tdmonth-\tdday\quad\tdhours:\tdminutes}}

\begin{document}
\begin{frame}{Frame title}
\dots
\end{frame}
\end{document}
