Json date format for Highcharts date format

Question

Can anyone advise me how to get such a datetime json object

{ value="01/01/2013 08:00", key=5.5 } 

in javascript (for use in Highcharts) datetime acceptable format

 [Date.UTC(2013, 0, 1,08,00), 5.5]. 

UPDATE

Here is what I am trying to do:

 var chart; $(document).ready(function () { chart = new Highcharts.Chart({ chart: { renderTo: 'container', zoomType: 'x' }, yAxis: { type: 'double', min: 0 }, xAxis: { type: 'datetime', labels: { formatter: function () { return Highcharts.dateFormat('%a %d %b %H:%M', this.value); }, dateTimeLabelFormats: { minute: '%H:%M', hour: '%H:%M', day: '%e. %b', week: '%e. %b', month: '%b \'%y', year: '%Y' } } }, series: [{ name: 'MyData1', data: [] }, { name: 'MyData2', data: [] }] }); chart.series[0].setData([ [Date.UTC(2013, 0, 1, 08, 00), 4.4], [Date.UTC(2013, 0, 1, 12, 00), 6.0], [Date.UTC(2013, 0, 1, 17, 00), 7.7], [Date.UTC(2013, 0, 1, 22, 00), 5.8] ]); chart.series[1].setData([ [Date.UTC(2013, 0, 1, 08, 30), 0.4], [Date.UTC(2013, 0, 1, 10, 00), 0.0], [Date.UTC(2013, 0, 1, 16, 00), 0.7], [Date.UTC(2013, 0, 1, 20, 00), 0.8] ]); }); 

here is in jsFiddle.

 var datatype1=[]; var datatype2= []; for(index in userReadingsJsonCollection.items){ if(userReadingsJsonCollection.items[index].ReadingsData.Reading_Type==type1){ datatype1.push( [Date.parse(userReadingsJsonCollection.items[index].ReadingsData.Rec_DateTime), userReadingsJsonCollection.items[index].ReadingsData.Reading] ); } if(userReadingsJsonCollection.items[index].ReadingsData.Reading_Type==type2){ datatype2.push( [userReadingsJsonCollection.items[index].ReadingsData.Rec_DateTime, userReadingsJsonCollection.items[index].ReadingsData.Reading] ); } } 

As a result, I get [[1357027200000,5.5]], and it works fine.

If your time is already UTC, it's simple:

 Date.parse("01/01/2013 08:00")

Assuming your data is returned as valid JSON:

 var jsonObj = {value:"01/01/2013 08:00", key:5.5}; var seriesOneData = []; seriesOneData.push([Date.parse(jsonObj.value),jsonObj.key]);
