is it safe to pass ISO8601 string in new date javascript code example

Example 1: get iso date javascript

var isoDate = new Date().toISOString()

Example 2: iso to date javascript

date = new Date('2013-03-10T02:00:00Z');
date.getFullYear()+'-' + (date.getMonth()+1) + '-'+date.getDate();//prints expected format.
