How To Properly Convert End_time Timestamp Into Date

I'm requesting data from Facebook Insights API with granularity set to a day, let's take likes as an example. My request goes to: PAGEID/insights/page_fan_adds_unique/day Response

Solution 1:

Actually, UTC-7 would be Pacific Daylight Time (PDT). Pacific Standard Time (PST) is UTC-8.

But reading the Facebook Insights documentation, in the FAQ it says:

All daily, weekly and monthly Insights data are aggregated according to PDT (Pacific Daylight Time).

That's a bit strange, as it would mean that -7 is used year-round, even when PDT is not in effect. But hey, if that's what's in the docs then I guess Facebook has their reasons.

Fortunately, this is easy to compensate for with moment.

date = moment(time).zone(7).format("YYYY-MM-DD");

For this operation, the time zone of your server or of the client does not matter.
