test fail: quantile(array, p) coerces values to numbers.

[geekplux]

run npm install after cloned this repo, a test fail occured:

# quantile(array, p) coerces values to numbers
ok 529 should be equal
ok 530 should be equal
ok 531 should be equal
ok 532 should be equal
not ok 533 should be equal
  ---
    operator: equal
    expected: 1309582800000
    actual:   1309579200000
    at: Test.<anonymous> (/Users/geekplux/Dropbox/project/github/d3-array/test/quantile-test.js:35:8)
  ...
ok 534 should be equal

is related to the time zone?   👀

I just fix it by changing:

  test.equal(arrays.quantile(dates, 1 / 2), +new Date(2011, 6, 2, 13));

to

  test.equal(arrays.quantile(dates, 1 / 2), +new Date(2011, 6, 2, 12));

Yes, the test was timezone-specific. I’ve changed it to use UTC dates.
