Shiv -

I would encourage you to make sure you are thinking very clearly  
about times and time zones in your app. There are many ways to shoot  
oneself in the foot in this area.

The thing that always helps me is to put it into Model-View- 
Controller terminology. Even complex problems can be simplified in  
this way.

For example, say two users are looking at the same info about an on- 
line meeting. One person is in Tokyo and the other is in Texas. How  
do we make sure that when they express an opinion about the meeting  
time, that they are not talking past each other. A meeting has to  
occur at one time. That is a model concept. If the users express a  
time preference, does the "time as model" of one agree with the "time  
as model" of the other? What if one person wants to see the time in  
UTC and the other wants Tokyo time? That is a controller issue. The  
UTC user wants the controller to tell him the time as if he was in  
England. What if one wants the time zone expressed as "- 0500" and  
the other as "Tokyo/Japan"? That is completely a view issue.

I can only work this stuff out when I separate the issues and deal  
with each separately.

Good luck and don't trip over the grave stones of those who have gone  
before you....
