Handling Time Zone differences when sending dates to javascript and reading back over AJAX

First convert to string:


string dateValue = lastRow.PublishDate.Value.ToLongDateString();
                string timeValue = lastRow.PublishDate.Value.ToLongTimeString();

Pass to javascript like this:


String.Format("javascript:fnDoWork(new Date('{0} {1}'));",
                                                                                                           dateValue,
                                                                                                           timeValue)

When you read back:

DateTime lastDate = rawDate.ToLocalTime();

Now, what you sent is what you will get on the server.

Best way is to make sure all dates in the database are stored in UTC to avoid such complications.
