現在のロケールに対応したISO 8601 拡張形式の日付文字列を返します。
現在のロケールが UTC (協定世界時) であるなら、Date.prototype.toISOString() と同じ文字列を返します。
第一引数で指定された date オブジェクトを元に現在のロケールで ISO 8601 拡張形式の文字列を返します。

console.log(toISOLocalString(new Date(2000, 1,2,3,4,5,6))); // "2000-02-02T03:04:05.006+09:00"第一引数が date オブジェクトではなかった場合、TypeError を返します。
