Date parse behavior change in node-v8 ?

[c0b]

this is the latest v8 nightly: it parses as a local timestamp:

➸ ./opt/node-v8.0.0-nightly20170524260cd411d4-linux-x64/bin/node -p 'new Date("2017-05-24T00:00:00")'
2017-05-24T07:00:00.000Z

vs. v7 and v6 below parse the same string always as UTC

➸ ./opt/node-v7.10.0-linux-x64/bin/node -p 'new Date("2017-05-24T00:00:00")'
2017-05-24T00:00:00.000Z

This could be why the ftp test has been failing in citgm for master. According to at least the ECMAScript 2018 spec this behavior is correct (I'm not sure if/when it changed though):

When the time zone offset is absent, date-only forms are interpreted as a UTC time and date-time forms are interpreted as a local time.

EDIT: It looks like this behavior may have changed in ES2015

Yes, that's correct. I'll close this out as working per spec but it's something we probably want to call out in the release notes.
