JavaScript new Date(string) returns different results on exactly identical date strings

I would like to share something I found with JavaScript today.

Simple example here

d1 = "2014-07-15T14:00:00.000Z"
d2 = "2014-07-15T14:00:00.000Z"

The input strings are ISO formatted using new Date().toISOString();. I received the first date from a server where it was stored in mongoDB as ISOString, and the second one was created manually.

If I do new Date(d1);, it returns 'Invalid Date' but if I do the same for d2 it returns the correct date.
