I've never met a normal English person, 
and probably would hate it when I would.

Normality is not something to strive for, 
and a dirthy mind should be a joy forever.

I would think there is no use for the replace function here.

However, I love Regex to much to go without, so:

function AddDow(match) { 
	return match +
	" " +
	new Date(match).toString().replace(/ .*/,'');
};

A normal person would perhaps prefer:

2014-01-10  14:29  free
2014-03-05  00:48  married
