Date.parse has been around since ES1 making a fallback seems a bit out of place. Also the workings of ES5/5.1 Date.parse are a bit too complex to fit in 140bytes.

currently, I can cope for the given Date's timezone:
function(a){a=a.split(/[^\w-]\D?/);return new Date(a[3],"anebarprayunulugepctovec".search(a[1])/2,a[2],a[4]+(0|a[7].slice(2,5)),a[5],a[6])}This doesn't take care of the local timezone, though - and I already got 139 bytes without the polyfill prefix.
