highcharts datetime axis，如何计算正确的时间戳？(highcharts datetime axis, how to comput correct timestamp?)

highcharts datetime axis，如何计算正确的时间戳？(highcharts datetime axis, how to comput correct timestamp?)

假设我想绘制一个系列，其中第一个点代表2013年11月5日11:30的时间。如果我在不同的时区使用浏览器查看我的图表，我希望时间11:30相同。 因此我想useUTC = true。 现在，我如何计算赋予highcharts的值（毫秒）？

我试过这个python代码：

>>> import datetime,time >>> t=datetime.datetime(2013,11,5,11,30,00) >>> time.mktime(t.timetuple())*1000 1383647400000.0

但是如果我在高位图中插入值1383647400000.0，我会得到一个时间点10:30而不是11:30。

这是一个重现故障的代码： http ： //jsfiddle.net/2BffA/6/

我究竟做错了什么？

Let say I want to draw a series where the first point represents the time 11:30 of november 5 2013. I want the time 11:30 to be the same if I look my chart with a browser in a different timezone. Hence I want useUTC=true. Now, how do I compute the value (milliseconds) to give to highcharts?

I tried with this python code:

>>> import datetime,time >>> t=datetime.datetime(2013,11,5,11,30,00) >>> time.mktime(t.timetuple())*1000 1383647400000.0

But if I plug the value 1383647400000.0 in highcharts I obtain a point with time 10:30 instead of 11:30.

Here is a the code reproducing the malfunctioning: http://jsfiddle.net/2BffA/6/

What am I doing wrong?

问题出在python代码中...构建UTC时间戳的正确方法是2013年11月5日11:30

>>> import datetime, calendar >>> t=datetime.datetime(2013,11,5,11,30,00) >>> calendar.timegm(t.utctimetuple())*1000.0 + t.microsecond * 0.0011383651000000.0 1383651000000.0

如果useUTC = true，这是发送到highcharts的正确时间戳

The problem was in the python code... The correct way to construct a UTC timestamp for 11:30 november 5, 2013 is

>>> import datetime, calendar >>> t=datetime.datetime(2013,11,5,11,30,00) >>> calendar.timegm(t.utctimetuple())*1000.0 + t.microsecond * 0.0011383651000000.0 1383651000000.0

which is the correct timestamp to send to highcharts if useUTC=true
