Answer 1

You can use the toJSON() method to get a DateTime style format

var today = new Date().toJSON(); 
// produces something like: 2012-10-29T21:54:07.609Z

From there you can clean it up...

To grab the date and time:

var today = new Date().toJSON().substring(0,19).replace('T',' ');

To grab the just the date:

var today = new Date().toJSON().substring(0,10).replace('T',' ');

To grab just the time:

var today = new Date().toJSON().substring(10,19).replace('T',' ');

Edit: As others have pointed out, this will only work for UTC. Look above for better answers.
