title: need to display timestamp in UTC as some other timezone and not browser locale in highcharts
body: <p>in the chart, i do not want to display the time in my local timezone, the timestamps are in UTC but it seems, highchart is displaying it in browser locale timezone. I just need to display this UTC timestamp in America/Edmonton. Please help. The options that I have is with setting timezone property in highchart but i already have in UTC, just want to display differently.</p>
  <pre><code>time: {
              timezone:'America/Edmonton',
              moment,
            },
  </code></pre>
  <p>also i saw we can add globalOptions with the same timezone property.. but how to do that in react?</p>
