Time zone differences, and all that jazz

The fun challenge about meeting from many eventual time zones is the fact that daylight saving is implemented differently in different US states, where some have adapted this procedure and others have not), and in Europe (where summer time is only actual in our calendar from the last Sunday of March - each and every year. For the Southern Hemisphere (Australia etc) this makes even more confusion as they are now moving into winterly hours.

Unfortunately, as I just tried to play with the Meeting planner at http://www.timeanddate.com I see that this does not appear to be accurately calculated either... http://tinyurl.com/cgj44j
