Date.parse() results in NaN
My jsFiddle works fine, but run it in my ide (both Aptana and WebStorm) shows NaN in the console.log() output.
Really confused about this...Is someone has such experience before?
Working demo http://jsfiddle.net/7KfuM/
Change - to /
var firstDayTimestamp = Date.parse("2009/07/13 00:00:00" + "-0500") / 1000;
Hope this fits the cause! B-)
The date should be in the IETF date syntax (RFC2822 Section 3.3) format, e.g. "Mon, 25 Dec 1995 13:30:00 GMT", or "Mon, 25 Dec 1995 13:30:00 GMT+0430".

Surprisingly this should be done also for the current (2017) versions of IE (11.x) and FF (56.x) for the Date.parse to work correctly.
