I am evaluating DNN and am confused by control of date formatting.

In my non-DNN sites, I use the iso standard for presentation and a javascript approach to validation of the various formts a user is likely to use, converting to iso in all cases. The database stores dates in its own datetime format of course. This solves all the date localization difficulties for me in that I don't localize  at all but use yyyy-mm-dd everywhere. I have found it to be the only effective route for my clients' sites that use multi-lingual resources and are used by browsers set to a wide range of locales.

I get the impression there is no overall control of date formatting that module writers can use - a format element in the web.config would be a simple way to manage this. I am worried that this will cause me significant problems when deploying DNN and a range of modules.

Is there a way to handle the issue of date formatting across a website that is used by DNN and all modules that I have not spotted yet?
