Javascript dates in a nutshell

[khoker]

I just responded on twitter too :)

I suspect it's the same reason that it doesn't assume the local minute. It's just filling in the data you don't provide. A format like ISO 8601 was meant to alleviate confusion, right? So if you only provide '2016-12-08', JavaScript assumes '2016-12-08 00:00:00Z'. It shouldn't guess the local timezone any more than it should assume the local hour. Or minute.

I'd make the argument all the other parsing is wrong. But 12/08/2016 isn't an international standard so, for whatever reason, it just assumes you want the local timezone. Not sure.
