The following is the application delcaration json file

```
{
  "apps" : [{
    "name"        : "test_v2",
    "script"      : "bin/www",
    "log_date_format"  : "YYYY-MM-DD HH:mm Z",
    "ignore_watch" : ["[\\/\\\\]\\./", "node_modules"],
    "watch"       : true,
    "node_args"   : "--harmony",
    "cwd"         : "/root/src/test_v2",
    "env": {
        "NODE_ENV": "production",
        "AWESOME_SERVICE_API_TOKEN": "xxx",
        "TZ": "America/Los_Angeles"
    }
  }]
}

```

To change the time zone, i had followed as commented at <https://github.com/Unitech/pm2/issues/560>

But it does not work. The behavior is the same as thought the "TZ" is not present. I tried even hard coding the time zone to numeric value like "+08:00" which does not work. How to change the time zone in the logs.
