time axis incorrect

[livni]

In this example http://jsfiddle.net/tCSzs/1/ the 1m bars time-stamp rises monotonically, starts at 2012-02-17 00:00 and ends at 2012-02-17 22:45, however the Highstock chart indicates as if the first bar is at 2012-02-16 16:22 and ends at 2012-02-17 20:45
How come?

And in this example http://jsfiddle.net/Yhq4m/ the bars seem to be shifted by 2h backwards in time. For this second example, could it be linked to the fact that I'm located at +2 to GMT?

The first "issue" is caused by dataGrouping (http://www.highcharts.com/stock/ref/#pl ... taGrouping). Yes, it can be caused by 2h shift. By default Highcharts uses UTC time, if you want to use client timezone you have to set useUTC to false (http://www.highcharts.com/stock/ref/#global--useUTC)

Regarding the first case - I don't understand how dataGrouping can cause such a shift in start\end times. Could you elaborate? Notice that the start time shifted back by 7h and 38m and the end time shifted back by 2h. What can I do to correct this?

Regarding the second case - I haven't changed the default and the data itself is UTC, so how come there's a shift?

1. Check attached screenshot to see what I've got, there is something like "22:00-22:29" - time for the group of points. I've never got something like "16:22" here.

2. This is your first timestamp: 1329429600000, try type this into terminal (remove 3 zeros from the end, JS uses miliseconds):

Code: Select all

$ date -ur 1329429600 // => Thu 16 Feb 22:00:00 2012 UTC

You'll notice what UTC time it is.

I have to admit that the errors were on my side. I was processing the timezones wrong in my backend python web framwork. Sorry for the confusion and thanks for taking the time to set me straight
