Question

I am trying to find a way to parse my data format so that it could be recognized by HighStocks. My data fetched from the server is in such format:

var data = [
    {
        "dt":"2010-06-10 14:33:39",
        "val":98
    },
    {
        "dt":"2010-06-10 14:34:18",
        "val":99
    },
    {
        "dt":"2010-06-10 14:34:28",
        "val":93
    },
    {
        "dt":"2010-06-10 14:34:38",
        "val":79
    },
    {
        "dt":"2010-06-10 14:34:48",
        "val":87
    },
    {
        "dt":"2010-06-10 14:34:58",
        "val":86
    },
    {
        "dt":"2010-06-10 14:35:08",
        "val":79
    },
    {
        "dt":"2010-06-10 14:35:17",
        "val":90
    }]

From the demo on Highcharts website it accepts format like:

var usdeur = [
[Date.UTC(2003,8,24),0.8709],
[Date.UTC(2003,8,25),0.872],
[Date.UTC(2003,8,26),0.8714],
[Date.UTC(2003,8,29),0.8638],
[Date.UTC(2003,8,30),0.8567],
[Date.UTC(2003,9,1),0.8536],
[Date.UTC(2003,9,2),0.8564],
[Date.UTC(2003,9,3),0.8639],
[Date.UTC(2003,9,6),0.8538],
[Date.UTC(2003,9,7),0.8489]]

So simply saying, how could I format my data 2010-06-10 14:33:39 to Date.UTC(2010,06,10,14,33,39)? Any JavaScript/jQuery method or existing libraries like date.js/moment.js allow me to do that easily (say if I don’t want to use getUTC*() to get the datetime information and then put into Date.UTC())

Thanks in advance.

Why don’t you format it on your sql ? It’s much better than format each point of your chart.
UNIX_TIMESTAMP should help you.
Example:
SELECT UNIX_TIMESTAMP(concat(dateColumn, timeColumn)) * 1000 AS 'dateUTC';
