Date.parse unit test fails in Saf5.1.1 about es5-shim

[Yaffle]

1e15 - 999999913600000 === 1 day

[Yaffle]

(!Date.parse || Date.parse("[phone]T00:00:00.000Z") !== 8.64e15) - works fine, so native Date.parse used in Safari 5.1, and native Date.parse('+033658-09-27T01:46:40.000Z') === 1e15 in Safari

[Yaffle]

same issue:
alert(Date.parse('2034-03-01T00:00:00.000Z') - Date.parse('2034-02-27T23:59:59.999Z')); // alerts 1 in Safari

so, es5-shim should replace native Date.parse for Safari

[Yaffle]

another Date.parse issue in Chrome:

Date.parse('1995-02-04T24:00') === Date.parse('1995-02-05T00:00')

24:00 - midnight is a special case and should be parsed, Chrome returns NaN...

Some tests (native Date.parse):

What is right results for this tests?

IMHO, Firefox implementaion is best, except "Date.parse("2012-04-04T24:00:00.500Z")"
