Cannot read property zoneName of undefined

On some windows 10 computers with non english language this error is thrown in Timezone/index.js. I think timezone guessing utility cannot detect it.

@jaynakus
Thanks for your feedback! I'll check it later.

Doesn't work on Chrome either in Europe.

moment.tz.guess() is using Intl.DateTimeFormat().resolvedOptions().timeZone which returns CET and getTzForName("CET") returns undefined

I added this in my local branch to getTzForName. Does solve the problem but I have no clue if it's a fix. Basically searching the abbreviation as well as the zone name if the first fail.

  if (maps.length == 0) {
    maps = tzMaps.filter(function(tzMap) {
      return tzMap['zoneAbbr'] === name;
    })
  }

full function now looks like:

var getTzForName = function getTzForName(name) {
  var maps = tzMaps.filter(function (tzMap) {
    return tzMap['zoneName'] === name;
  });
  if (maps.length == 0) {
    maps = tzMaps.filter(function(tzMap) {
      return tzMap['zoneAbbr'] === name;
    })
  }
  return (0, _func.head)(maps);
};

Sorry guys, I'm taking a vacation these days and just see your comments. First of all, many thanks for your feedback! But it really works well for me, so I have to do more debug to check, and maybe use @gnilk 's solution to publish a small bugfix version to check if it help.

Publish a new version V2.2.2, using your @gnilk solution, thanks. Your can update and check if it works.

Seems to work. Thanks!

I am using a version 2.2.10 and I still have the problem mentioned above. Does the version 2.2.10 support predefined property "timezone" and would that inhibit the error? Unfortunately I do not have a Windows 10 at hand and I am stuck using this older version of react-times.
