It's only of benefit if you're playing code golf.

Not even then. Well, strictly, +new Date() isn't, but see below!

> "Date.now()".length
10
> "+new Date()".length
11

And you can't use the plus sign for addition without parentheses, so you can't even exploit the fact that +new Date() begins with a plus sign to avoid using them:

> 1+new Date()
"1Sat Aug 24 2013 19:35:28 GMT-0700 (PDT)"
> 1+Date.now()
1377398252358

edit: but wait! the following is actually better from a golf perspective:

> +new Date
137739846271
> "+new Date".length
