wrong Date after year 2834

[baabgai]

1. Which version of PhantomJS are you using?

   Version: 2.1.1

2. What steps will reproduce the problem?

   1. call new Date('2900') or any date string higher than the year 2834

3. Which operating system are you using?

   OSX 10.11.6

4. Did you use binary PhantomJS or did you compile it from source?

   binary distribution using npm install phantomjs-prebuilt

5. Please provide any additional information below.

The machine is configured to CET local time. Not sure if this has any impact on that specific problem.
The problem is that that any call to new Date() using a year higher than 2834 the resulting date will be off by one day

e.g. in phantomjs shell

new Date('2835') // => "2834-12-31T00:00:00.000Z"

in node (v6.4) the result looks like

new Date('2835') // => "2835-01-01T00:00:00.000Z"

in Chrome (54.0.x) the result is

(new Date('2835')).toISOString()  // => "2835-01-01T00:00:00.000Z"

I think it's related to #14506

Could you please try it again but with 2.5 version?

Due to our very limited maintenance capacity (see #14541 for more details), we need to prioritize our development focus on other tasks. Therefore, this issue will be automatically closed. In the future, if we see the need to attend to this issue again, then it will be reopened. Thank you for your contribution!
