ERROR: Unable to draw analogue clock face. Why?


David Gibson

On the Internet since 17th May 1994. You wont find me on Facebook or Linked-In. I only rarely tweet at @I_amDavidGibson. I live in Leeds, UK.

* My Speaking Clock doesnt actually speak - you have to do the talking yourself. See: Speaking Clock. Unlike the clock on the BBC's web site (see news item here) my clock is accurate!.

This web page will attempt to obtain an accurate time setting from the web server. If this message alters, it has been successful. Your computer's local clock may well be wrong.

If this text appears for more than a fleeting moment then something may have gone wrong, e.g.

  • The web server is slow in responding

  • You are running an old version of JavaScript
  • There is a programming error - my fault
  • Your computer is still 'thinking about it'


I have an MA degree in Maths / Engineering from Cambridge University and a PhD from the University of Leeds (School of Electronic and Electrical Engineering). From 1 Jan 2016 I have been a Senior Research Fellow at the University of Exeter's Camborne School of Mines (College of Engineering, Mathematics and Physical Sciences). See staff profile although, since Im only on a medium-term contract, that might eventually disappear, to be found only in the Internet Archive at the Wayback Machine.

Selective lists of my publications are given on my University of Exeter page, and at ResearchGate. You can also search the CREGJ database and take a look at my Cave Radio web page. If you've come here because of a professional interest then you will already know my fields of work and that Im available for consultancy and contract work – Please email me for a version of My CV that includes full contact information (The online version has been redacted).


1 January 2012: I have removed most of the content of this web page, as it was all getting rather out of date. Perhaps I'll edit it and replace it one day? Places to go...
