[GitHub] [incubator-echarts] wlbksy opened a new issue #13073: wrong timestamp parser when xAxis type is 'time'
wlbksy opened a new issue #13073:
URL: https://github.com/apache/incubator-echarts/issues/13073
### Version
4.8.0
### Steps to reproduce
following timestamp is around 2020-08-04 10:11:00
```javascript
option = {
xAxis: {
data: [1596507060, 1596507160, 1596507260], // second
type : 'time'
},
yAxis: {},
series: [{
type: 'line',
data:[220, 182, 191]
}]
};
```
```javascript
option = {
xAxis: {
data: [1596507060000, 1596507160000, 1596507260000], // micro second
type : 'time'
},
yAxis: {},
series: [{
type: 'line',
data:[220, 182, 191]
}]
};
```
```javascript
option = {
xAxis: {
data: [1596507060.000, 1596507160.000, 1596507260.000], // second with decimal
type : 'time'
},
yAxis: {},
series: [{
type: 'line',
data:[220, 182, 191]
}]
};
```
### What is expected?
right parsing of x axis timestamp, timestamp is around 2020-08-04 10:11:00
### What is actually happening?
timestamp displays 08:00:00, and wrong xaxis interval

It may be not a bug but an incorrect usage. `xAxis.data` is just for the type of `category`. If the type is `time`, it can't be specified.
> [Category data, available in type: 'category' axis.](https://echarts.apache.org/en/option.html#xAxis.data)
When the type of xAxis is `time`, the time should be specified as a dimension in the `series.data`.
**Example:**
```js
option = {
xAxis: {
type : 'time'
},
yAxis: {},
series: [{
type: 'line',
data:[
[1596507060000, 220],
[1596507160000, 182],
[1596507260000, 191]
]
}]
};
```

@wlbksy I'm afraid we can't. For a numerical timestamp, ECharts will parse it to a Date object by `new Date(timestamp)`.

@plainheart One more question, could we use Standard Unit like seconds as default timestamp unit, instead of javascript's milliseconds?
