Year in moment JS defaults to 1900 instead of 2000?

Question

moment("05/1/11").toString() returns "Mon May 01 1911" not 2011 as expected.

In Moment.js documentation I see "2 digit year (if greater than 68 will return 1900's, otherwise 2000's)" multiple times (for year, week, and ISO year).

I would expect moment to follow this by default when parsing a date without a format, but it doesn't. Is this a feature? Is there a way to force it to behave this way (2000 if less than 68) for years anyway?

I need to parse free-form user input. It might be 5/1/11 it may be July 5 11 or July 6, 2011. So the only format I wish to pass into to moment is for the years field, and then only if a four-digit year is not found in user input.

If you don't specify a format string, the parsing is handled by the browser (i.e. new Date(string)), not by Moment; see the documentation for moment(string) in the docs. If you want Moment to do the parsing (and apply rules like > 68), you need to provide the format string.

var test = moment("05/1/11", "MM/D/YY").toString();
$('#date').append(test);
