Javascript Agent does not respect timezone

[elvetemedve]

When I set the "TIMEZONE" environment variable to a zone other than the one set on the host, GUI will reflect the changes, but when a Date object is created from a Javascript Agent, it will use the time zone of the host machine instead of the application.

Steps to reproduce the issue:

1. Set up a docker container following this guide https://github.com/cantino/huginn/blob/master/docker/multi-process/README.md and set the TIMEZONE=Budapest environment variable too.

2. Start the application

3. Create a new Javascript Agent, give it a name like test, and put the following lines to the code field:

   Agent.check = function() {
       var date = new Date();
       this.createEvent({ 'time': date.getHours() + ':' + date.getMinutes()  });
   };
   Agent.receive = function() { 
   };

4. Click on the Dry Run button twice.

You will get a time which is in UTC. The expected time should be in UTC+1 (Europe/Budapest zone).

A quick workaround is to run sudo dkpg-reconfigure tzdata inside the Docker container and restart it after that.

Thanks for reporting the issue and pointing in the right direction @elvetemedve . It looks like setting the TZ environment variable has the same effect as configuring the timezone system wide. Would you mind testing the change I made in #1356?

@dsander I've tested your changes and I can confirm that it works well. Well done. 👍
