ASP.NET MVC3 自定义转换输入参数的最佳方式

Question

I'm going to add support of different timezone in my ASP.NET MVC3 app.

The solution is to store date values in UTC time, and store user timezone offset.

So, I need 2 things:

1. Send date values to user in "user time" (it's clear, I pass date to wrapper that convert time to user time)

2. Retrieve date from user in "user time" and convert it to UTC.

Question is - what is the nice way to convert all input date values to UTC time. Or is there a generic way to add some converting rules to ASP.NET MVC?

This is ideal schema what I want (controller receive already converted values)

A way could be to create your own ModelBinder that do the work of mapping and preparing the data for your action method in the controller.

This post from Hanselman's Blog should give you an idea of what I mean. Obviously I'm assuming that you can get all the data you need inside the method

BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext);

Like getting the user timezone with a repository or a hidden field in the post.
