Patch Node.js console methods in order to add timestamp information by pattern.

npm install console-stamp
// Patch console.x methods in order to add timestamp information
require("console-stamp")(console, "HH:MM:ss.l");

console.log("Hello World!");
// -> [14:02:48.062] [LOG] Hello World!

var port = 8080;
console.log("Server running at port %d", port);
// -> [16:02:35.325] [LOG] Server running at port 8080
console.time( "MyTimer" );
console.log( "LOG" );
console.info( "INFO" );
console.warn( "WARN" );
console.error( "ERROR" );
console.dir( { foo: "bar" } );
console.trace();
console.timeEnd( "MyTimer" );
console.assert( count < 10, "Count is > 10" );

Result:
