Ok, here's my issue. I can't find anything that explains how DNN deals with daylight savings time. Also I can't see where the time zone offsets are stored. They aren't in the DB, you'd think they'd be under lists but they aren't. The time zone editor lets me change the names of an offset but doesn't let me change what the offset is. If anyone can provide guidence on this I'd appreciate it. I've got a person who says they'd rather not do DNN because of the Time zones and daylight saving stuff.

Ok, so it's impossible to manage time zone to DST. I'm finding more stuff saying that. But wait.....

I know that the portal can choose it's time zone and so can the user and that is stored as part of it's settings. But the actual data comes from somewhere. The dime zone editor. Where is this data stored. Please tell me that's not hard coded!!!  By the way, because this is such a touchy subject and it can't really be automated. It needs to be made easy for administrators. To be honest. I'm not sure why this wasn't already done. This is just an idea of where I would go with this.

First, I'd have a table that defines the timezone data, just like the Permissions table
Then for the settings on the user and the portal, change it from storing the minutes to the id in the new table
Then add a new setting for the user and the portal where you ASK them if they use DST.
Now you have everything you need. You could also add some new skin objects called currentsystemtime and currentusertime.
