Support displaying arbitrary time zone settings.

[jblz]

It appears that the visualization displays data points based on the client browser's timezone offset and I can't seem to change it.

I can hack my data object by adding (new Date( timestamp * 1000 )).getTimezoneOffset() * 60 to each of the keys to make it display in UTC (desirable in my application).

Here's an example which illustrates this:

It would be nice to be able to supply an offset to override the client when the data being visualized are in a different time zone.

Up ? It's been a year now, have you been able to have a look at it ?

I'd like to +1 this as well, though I'm thinking maybe we should provide an afterLoadData snippet in the meantime.

So, for everyone scratching their heads at this issue in the future: here's a pollyfill

@wa0x6e any updates on this?

I am experiencing an issue that is possibly related. Timestamps are stored with the correct dates, but Cal Heatmap highlights the wrong date (highlights the previous day):

Timestamp (human time):

Saturday, August 5, 2017 12:00:00 AM

indeed, the calendar is always using the browsers' timezone. Customizing the timezone is in the todo list.

@wa0x6e Thanks for the response. Any idea on when this could occur?

Just figured out that this is probably why Pagure user activity heatmaps are frequently off by a day for users in timezones a long way from UTC (see this downstream issue).
