Notes: 1) If unspecified, the month / day defaults to the current month / day, the time defaults to midnight, while the timezone defaults to the browser's timezone. If a time is specified, it must include both hours and minutes. The "T" delimiter, seconds, milliseconds and timezone are optional. 2) The decimal fraction of a second, if specified, must contain at least 1 digit (there is no limit to the maximum number of digits allowed), and may be delimited by either a '.' or a ',' Refer to the examples on the right for the various levels of date-time granularity which are supported, or see http://www.w3.org/TR/NOTE-datetime for more info.
