I've got a date format which looks like this: 2017-02-18T09:00:00+06:00.

This is the format I'm trying to parse it with: d3.utcParse("%Y-%m-%dT%H:%M:%S+%Z");, but it returns null.

Any ideas? Thanks!

Instead of

d3.utcParse("%Y-%m-%dT%H:%M:%S+%Z");//+ is not needed

It should have been

d3.utcParse("%Y-%m-%dT%H:%M:%S%Z")

working code here

Your parsing specifier is not correct. The + in the timezone +06:00 is actually part of the timezone and must not be included in the specifier string.

var parser = d3.utcParse("%Y-%m-%dT%H:%M:%S%Z");

console.log(parser("2017-02-18T09:00:00+06:00"));

<script src="https://d3js/d3.v4.js"></script>

That looks like an ISO 8601 datetime string. Why not try isoParse instead of utcParse?

d3.isoParse('2017-02-18T09:00:00+06:00')

For me this returns:

2017-02-18T03:00:00.000Z

Which is a correctly timezone-adjusted UTC datetime.
