javascript - Convert set date to user's local time automatically -


i creating application have pretty big set of dates , times, , need display these in user's local time , date. set dates , times in bst; example 08-24-2014 16:00 bst = 08-24-2014 11:00 est. now, before coming here spent 3-4 hours looking answer if anything, got more confused. is there way, convert set of bst dates , times user's local settings automatically without them setting time zone etc?

p.s.: have 2 ideas in mind don't know if work nor how execute them.

1) , change bst date , time , convert unit of measurement; , change user's local date , time , covert same unit of measurement above, calculate difference in new measurement, , convert user's local time.

2) use geolocation find user's date , time/ time zone and; convert bst whatever geolocation spits out.

you can users machine timezone in javascript:

var currentdate = new date(); var currenttimezoneoffsetinhours = currentdate.gettimezoneoffset() / 60;

see documentation here: https://developer.mozilla.org/en-us/docs/web/javascript/reference/global_objects/date/gettimezoneoffset

having offset can add values

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
