@andyearnshaw @caridy Hi. I made ci tests run completely and I'd like to keep this PR as fix only the thing if it's ok. Could you please take a look into this when you have a time? Here are the results of ci tests:

Thanks.

@watilde thanks a lot for the help, I will be merging this later today.

@watilde I went on and fixes the whole test harness to be able to run the latest test, locally, I'm getting 99 passing correctly, no failures, that's a huge improvements :), thanks a lot again.

On travis I'm getting few failures:

• "passCount": 553,
• "failCount": 18,

But this is a huge step in the right direction.

@caridy Wow I'm glad to hear that! I was trying to fix failed errors too, for latest tests(= grunt update-test262) on my local.

As a first point I started fixing 6.4 Timezone Names but finally I couldn't fix it. There was no way to get user's current time zone correctly because it's implemented in platform codes(e.g. win32, macos) and there is no interface without Intl native Object currently. Hence, I knew the reason why it was mentioned as Not Implemented in the README.md of this project. Well, I'm happy to support fix tests😃
