localised-date.html

<span id='date-me'></span>
<script type='text/JavaScript'>document.getElementById('date-me').innerHTML = new Date(Date.parse('Wed, 09 Aug 1995 00:00:00 GMT')).toLocaleString()</script>

My idea is to write an HTML helper in ASP.NET MVC that can convert a datetime to a local date, and you don't need to do anything but supply the date.

I'll have to generate the IDs uniquely, probably by field name with some prefix or suffix.

The date information will come from the .NET DateTime object, and will need filling in slightly laboriously (as in .GetYear() .GetMonth() etc) as JavaScript doesn't seem to have a native way of parsing UTC dates, and I'd rather not use a library like moment.js so that the helper always works and has no dependencies.

Update: I found Date.parse() does work with UTC as long as the string is formatted in one of a few supported ways.

I think outputting a DateTime as RoundTrip ought to do it.

Might need to set the DateTimeKind first:
