Gst.DateTime.prototype.to_iso8601_string

function to_iso8601_string():String {
    // Gjs wrapper for gst_date_time_to_iso8601_string()
}

Create a minimal string compatible with ISO-8601. Possible output formats are (for example): 2012, 2012-06, 2012-06-23, 2012-06-23T23:30Z, 2012-06-23T23:30+0100, 2012-06-23T23:30:59Z, 2012-06-23T23:30:59+0100

Returns: a newly allocated string formatted according to ISO 8601 and only including the datetime fields that are valid, or NULL in case there was an error. The string should be freed with GLib.free.
