HJG 2012-02-02 This is a small and simple program to show the time at some selected places around the world.
With some tweaks to the tcl-console.

BTW, there is a worldtimeclock buried in the tk-demos that come with ActiveTcl,
look for "Paned Windows and Notebooks / Themed nested panes".
HJG 2013-09-13 - Here is an extended version Worldtime-clock2 that offers a "running" clock.
It also does a "flash" every 10 seconds.
You can change that to 60, to get a flash at every full minute.

#.I made cs and td global (as in ::cs) for debugging & experimenting only,
to make access to them from the commandline more easy (e.g. enter puts "$cs $td" ).
