intlDate/formatDate fails on IE8 when passing in ISO date format #38

Closed lalau closed 9 years ago

On IE8, this call returns NaN for ISO date format. The call is made as new Date('2014-09-19T20:37:21Z').getTime(). It seems IE8 does not recognize this format, while newer IE and other browsers work for these. I would expect a polyfill to handle this case.

IE8 is one of the targeted browsers. We will investigate this in more details.

Is there a sensible approach to polyfilling this? I'm tempted to require numbers or Date objects.

We're not going to change or add the date parsing features built into the runtime. If IE8 can't parse the ISO string into a valid Date instance, then it won't work. If you're stuck with ISO dates in your DB or something, then you might want to find a lib that can parse them into valid Date instances before passing them o the helper.
