toLocaleString() not returning the right date format in node.js

In chrome's console:
(new Date(Date.now())).toLocaleString() returns "9/5/2014 9:43:08 PM"
new Date(Date.now()) returns 'Fri Sep 05 2014 21:43:08 GMT+0530 (IST)'

In node.js REPL/app:
(new Date(Date.now())).toLocaleString() returns 'Fri Sep 05 2014 21:43:18 GMT+0530 (IST)' which is the same as running new Date(Date.now())

What is the change I need to do to get the same output format as chrome.
