As I actually USE a clients time offset, I know what the problem is. The DATA 
is ALL stored as UTC time data, so it does not matter who enters it. It will 
be stored without a time offset.
When building a calender of events, I need to know the clients daylight saving 
time - since it is not available in the browser we have to handle it manually 
anyway so the browser feed is always a waste of time since it simply does not 
give you any USEFUL information. If I am building a calender of events over a 
change in daylight saving I NEED to know !!!
Now it would be possible to ignore time zone and daylight saving when storing 
data, but THAT becomes an even worse mess when trying to manage meetings 
across Europe. They can all be at 9AM but not happening at the same time as 
you have to track the daylight saving at each location :)

Correct, so people select the timezone that gives the right time, if the 
daylight saving switch is off. And then the calendar gives the wrong times 
when trying to display a weekend containing a daylight saving change. ( THAT 
one wasted a few hours before we twigged what was wrong - since the clock was 
right :) )
