title: Combining time and date in ISO8601 format string using Swift
body: <p>I have two texfields representing date and time from the date picker, but when I parse the string only the date is displayed. I would like to combine date and time into a string in ISO8601 format (e.g. <code>2015-06-11T00:00:00.000Z</code>) and send it to the server.</p>
