Well, the thing is that any Date that gets send to a WebService by Flex will be passed in a string format that does include timezone information (in Flash/Flex, you cannot have Date objects without any time information - even if you set hours, minutes, seconds to 0 the Date still carries time information)
If I would send a Date object from Flex just in this moment it would be passed as a string that looks approx. like this: 2006-06-16T18:49:00Z So, on my local machine it's 20:49h (or 8:49pm) as I'm located in Germany (that's UTC+1 plus 1 hour for daylight saving, so effectively it's UTC+2 - that's why it's sending 18:49 - it's my local time in UTC time) Basically, all you have to do in .NET is to handle the dateTime as UTC and make sure to always return UTC dates back to Flash/Flex.
