# Show clock in beamer presentation

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
• @Werner, I need to count the time of my presentation. – BetterEnglish Nov 18 '13 at 20:05
• @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
• You can use impressive. It has a clock with t shortcut. impressive.sourceforge.net – user11232 Nov 18 '13 at 23:07

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}
