highcharts gets my hour time wrong

问题

I'm from venezuela just in case. I doing a real time system where I get in my db the time,seconds and miliseconds like 10:39:09:2

I apply the strtotime($time) then I sended by json to charted

and in my highcharts i got in the

xAxis: {
  type: 'datetime',
  title: {
    text: 'Tiempo'
  }

the utc function is already false

Highcharts.setOptions({
  global: {
    useUTC: false
  }
});

and my function to get the json is

function requestData_Frecuencia() {
  $.ajax({
    url: 'Datos_Frecuencia.php',
    success: function (point) {
      var series = chart_Frecuencia.series[0],
        shift = series.data.length > 400;
      //add point
      chart_Frecuencia.series[0].addPoint(eval(point), true, shift);
      setTimeout(requestData_Frecuencia, 500);
    },
    cache: false
  });
}

PS. is been a while since I write in english so forgive me if I write something wrong o that isn't clear.

回答1:

You should check the raw values in the database. I know that MySQL stores dates in GMT. Not sure about the DB you are using, but the reason that this is done is:

GMT is an absolute time reference & doesn't change with the seasons.

You will have to convert the time to your locale, which is UTC–04:30

Have a look at: Convert date to another timezone in JavaScript

回答2:

Highcharts doesn't include timezones and only what you can do is disabling UTC,aas you have. THen you need to translate your data or use label formatter / tooltip formatter to display correct data.

I found out what I was doing wrong (found the answer here ). I used to get my time in php like:

while($r2 = pg_fetch_array($sth)) {
    $hora = $r2['hora'];
    $Frecuencia  = $r2['frecuencia'];
}
$x=strtotime($hora);

I needed to multiplied by 1000 the time. I think, is because I need to suggested that date is in form of miliseconds (that is integer)

while($r2 = pg_fetch_array($sth)) {
    $hora = $r2['hora'];
    $Frecuencia  = $r2['frecuencia'];
}
$x=strtotime($hora)*1000;

PD: thanks to everybody anyway for the suggestion and responses given. I really appreciated
