Instead of hosting the videos yourself you can upload them to any of a long list of video sites such as YouTube and use this plugin to display them on your Joomla! site.
Very easy to set up, good documentation and it works like a dream - thank you www.joomlaworks.gr
Personally, I don't use all the different time zones, but use it as a simple clock to show visitors the time at the location of the web site. This is very useful if you don't want people from overseas telephoning you out of hours!
The great thing about Time Zone Clock is that it doesn't rely on your computer clock, so it doesn't matter what the time your computer thinks it is - it will always show the correct time.
The module is very clean and neat - no bells or whistles or annoying Flash graphics - just a straightforward, easy-to-install clock that can simply and successfully be used for a number of purposes.
