Things like:

  var d =3D new Date(2012,9,3)=20

are entirely consistent in every browser, I see no need to use any other me=
thod to create a date object.

If the requirement is to create a date object for 1970-01-01T00:00:00Z, the=
n you might be correct (even ignoring the obvious "faster than what?"). But=
 that is likely an infrequent scenario.

Usually a date object is required to be set to a specific value other than =
the epoch, so what is the benefit to creating the object then setting its v=
alue (requireing at least one and maybe two further calls) over creating th=
e object and setting its value in one call?
