I've got a javascript that provides me with the timezone for the

So really simplistically
var timezone = jstz.determine_timezone().timezone
Time.zone = timezone.olson_tz
obviously this can't be done. I've taken a look on the web and can
only find 'solutions' over two years old and as ROR moves so fast I
thought someone may know of a better solution. So can anyone
suggest a
simple solution?
It needs to be set on the server. You could do an AJAX call.
Or, you could do this all in JavaScript, and simply translate the
dates in the browser. Store -- and display -- one time zone, like UTC.
But then on the client, collect all your dates (wrap them in a
span.date or something that you can get using JS) and use the client's
notion of the time zone to adjust their display on screen.
$$('span.date').each(function(elm){
var d = new Date();
var offset = d.getTimeZoneOffset() * 3600 * 1000;
var adjusted = new Date(elm.innerHTML);
adjusted.setTime(adjusted.getTime() + offset);
elm.update(adjusted.toLocaleDateString());
});
