Timezone support? #43

Closed BreadMaker closed 8 years ago

BreadMaker commented 9 years ago

I'm struggling trying to add timezone support for my little project, but I can't yet figure out how to show the data (which is in UTC) to UTC. Instead of that, I get the translated time (UTC-3) in my case. I'm missing something?

I have a similar timezone question. My data is in unix timestamp format. I need to visualize the data for EST (New York) and account for Daylight Savings Time. Does anyone have any pointers on how to go about this? Thank you!

@BreadMaker I was having the same issue. Turns out this is a d3 issue, not specific to timeline. I had used this from one of the examples:

.tickFormat( //
        {format: d3.time.format("%I %p"),
        tickTime: d3.time.hours,
        tickInterval: 1,
        tickSize: 30})

d3.time.format returns localized times. You want d3.time.format.utc(...) That got me UTC labels for my tick marks instead of local time.

Wow, that points at the right direction. Thanks @ryanfox !
