[lolq9]

Hi,
Can You explain how this format is work? It is hard to understand for me ;)
Bellow is some example (https://canvasjs.com/docs/charts/chart-options/data/xvaluetype/)

data: [
{
type: “column”,
xValueType: “dateTime”,
dataPoints: [

{ x: 1088620200000, y :71},
{ x: 1104517800000, y : 55 },
{ x: 1112293800000, y: 50 },
{ x: 1136053800000, y : 65 },
{ x: 1157049000000, y : 95 },
{ x: 1162319400000, y : 68 },
{ x: 1180636200000, y : 28 },
{ x: 1193855400000, y : 34 },
{ x: 1209580200000, y : 14 },
{ x: 1230748200000, y : 34 },
{ x: 1241116200000, y : 44 },
{ x: 1262284200000, y : 84 },
{ x: 1272652200000, y : 4 },
{ x: 1291141800000, y : 44 },
{ x: 1304188200000, y : 11 }

@lolq9,

This format is termed as Timestamp. The Unix timestamp is a way to track time as a running total of seconds. This count starts at the Unix Epoch on January 1st, 1970 at UTC. Therefore, the Unix timestamp is merely the number of seconds between a particular date and the Unix Epoch. For more information, kindly read this Wikipedia article. In JavaScript, a timestamp is the number of milliseconds that have passed since January 1, 1970, hence you need to multiply the Unix timestamp by 1000 to convert it to JS timestamp.

OK, so this is a great assistance. However, how do I explain to the Chart that I want the dates displayed in my time zone?

@jhodgeswaterford,

You can use the toLocaleString() method to convert a Date object to a string, using locale settings. The timeZone argument of toLocaleString() are used to parse and output dates that are in UTC or local time to a specific time zone.
