I guess you didn't understand my question. I am quite familiar with converting a datetime object from one timezone to another. The point of my question is that if I enter lets say 21.02.2011 14:45 as the selected date, I want to receive the same , but as it is in UTC. Instead, I receive it in some other timezone, and it is automatically converted to UTC with the other timezone's offset. I don't want that offset.
For example if I enter 21.02.2011 14:45,
and I want to use it in my code as 21.02.2011 14:45 (UTC)
insted the date on the clientside is 21.02.2011 14:45 (SOME OTHER TIMEZONE, -4h OFFSET FOR INSTANCE)
and it becomes when I access it server-side 21.02.2011 18:45 (UTC) because of the other timezone's offset.
I hope this makes it a bit clearer. The problem is not that I have to convert, but the mysterious timezone that comes with the date. If there is a standard way of determinig what is that timezone so I can do the conversion in a generic way, it will be fine.
