javascript - Wrong date in tooltip in charts with daylight savings time in highcharts -

i have chart dates 1 of days daylight saving day. days after day have there date in tooltip shifted minus 1 day.

$(function () { highcharts.setoptions({ global: { useutc: false } }); $('#container').highcharts({ xaxis: { type: 'datetime' }, chart: { type: "column" }, plotoptions: { series: { stacking: "normal" } }, series: [{ data: [{ y: 10 }, { y: 20 }, { y: 10 }], pointinterval: 86400000, pointstart: 1414274400000 //sun oct 26 2014 00:00:00 gmt+0200 (cest) }] }); });

example: http://jsfiddle.net/bmmg8jnx/

what date saving day?

do mean daylight savings time?

that create sense, if sending time stamp of midnight, , loses hour, read previous day. can work around sending stamp later in morning, or @ noon, or whatever point not @ start/end of day, , hence won't affected shifts of 1 hour.

{{edit reflect comments:

1) tooltip reflect value of x axis. notice point not on tickmark. tickmarks not placed match info points, placed @ set intervals. info behind interval hour, , hence tooltip reflecting date of info point.

2) offset of nature doesn't impact anything. unless info points representing happens every night @ midnight, case in info i've seen or used.

if info sending off hour, it's going off hour, , if hr pushes time previous day, date going off day. chart handling correctly based on have provided it.
