Solution 1:

I know this isn't a direct solution to your problem, but it may help anyway.

If you want a fully featured date library that doesn't modify the native Date object, I wrote one called Moment.js.

It provides a lot of the things that DateJS provides (formatting, parsing, manipulation, timeago, i18n, etc), but it's smaller, faster, and doesn't ruin the native date prototype.

Solution 2:

Nope, this is the intended design of date.js. It adds to the "prototype" of the Date object. Some people hate that, some people like it - but you've uncovered one of the drawbacks of this design.

Solution 3:

You can tell Highcharts to not use UTC date:

Highcharts.setOptions({global: {
        useUTC:false
    }
});

You should do this before you create the chart. Then you won't have to worry about converting your dates to UTC, it will be easier.
