Do I have to manually run date command using child_process and fetch the result from it to get the date? Is there any other way using node?
You do that as you would in a browser:
var datetime = new Date();
console.log(datetime);To create a new Date object in node.js, or JavaScript in general, just call it’s initializer
var d = new Date();
var d = new Date(dateString);
var d = new Date(jsonDate);
var d = new Date(year, month, day);
var d = new Date(year, month, day, hour, minute, second, millisecond);
Remember that Date objects can only be instantiated by calling Date or using it as a constructor; unlike other JavaScript object types, Date objects have no literal syntax
