Javascript 如何解析highcharts的JSON

我有一个JSON：

var z =   [{
        "signed_up": "2015-08-24T10:31:48.294Z",
        "sessions": 10,
        "browser_family": "Chrome",
        "browser_version": "44.0.2403",
        "timestamp": "2015-08-26T08:36:43.973725Z",
        "useremail": "test@test",
    },
    {
        "signed_up": "2015-08-24T10:31:48.294Z",
        "sessions": 10,
        "browser_family": "Chrome",
        "browser_version": "44.0.2403",
        "timestamp": "2015-08-26T08:36:02.765142Z",
        "useremail": "none",
    },
    {
        "signed_up": "2015-08-25T13:57:00.181Z",
        "sessions": 1,
        "browser_family": "Opera",
        "browser_version": "31.0.1889",
        "timestamp": "2015-08-25T13:57:00.181781Z",
        "useremail": "test1@test",
    },
    {
        "signed_up": "2015-08-24T10:31:48.294Z",
        "sessions": 10,
        "browser_family": "Chrome",
        "browser_version": "44.0.2403",
        "timestamp": "2015-08-25T13:53:43.198419Z",
        "useremail": "none",
    },
    {
        "signed_up": "2015-08-24T10:31:48.294Z",
        "sessions": 10,
        "browser_family": "Chrome",
        "browser_version": "44.0.2403",
        "timestamp": "2015-08-25T07:36:39.891389Z",
        "useremail": "test2@test",
    },
    {
        "signed_up": "2015-08-24T12:58:24.480Z",
        "sessions": 1,
        "browser_family": "Chrome",
        "browser_version": "44.0.2403",
        "timestamp": "2015-08-24T12:58:24.480428Z",
        "useremail": "none",
    }];

如何在“X”日期和“Y”时间行中显示

我不知道这是怎么回事。我尝试使用

array[]

并在两个不同的数组中推送日期+时间

对我来说最好的解析如下所示：

[
 ["2015-08-09", "12:33:12"],
]

highcharts希望日期和时间的格式是什么？不希望转换为整数格式，并在包含在highcharts中后转换？如何转换？时间戳是否大于1440510823198？但是如何在X日期和Y时间中显示呢？1440510823198 I format line new Data（）.getTime（）您可以使用date.UTC（）将数据作为时间戳返回。
