Is there any way to set other time zone in rally's log?  
I tried modify the format or datefmt in logging.json, but can't figure it out.

```auto
"normal": {
      "format": "%(asctime)s,%(msecs)d %(actorAddress)s/PID:%(process)d %(name)s %(levelname)s %(message)s",
      "datefmt": "%Y-%m-%d %H:%M:%S",
      "()": "esrally.log.configure_utc_formatter"
    }

```

Hello,

As you've shown in the above snippet, the [actual function](https://github.com/elastic/rally/blob/71688bcf5175cd1330481e8021f51d9c525785e1/esrally/log.py#L29-L36) that is currently used forces the output to UTC.

Depending on what you need to do and depending on how you've installed Rally, one workaround would be to edit the file [rally/log.py at 71688bcf5175cd1330481e8021f51d9c525785e1 · elastic/rally · GitHub](https://github.com/elastic/rally/blob/71688bcf5175cd1330481e8021f51d9c525785e1/esrally/log.py#L35) and e.g. switch from `time.gmtime` to `time.local` to honor the local timezone defined on your host.

We could probably support an additional property to specify a timezone for logging; I'll create a Rally issue.

@vsop_479 Can you please share why using local time would help? Sticking to UTC [avoids a lot of complexity](https://github.com/elastic/rally/pull/1699#pullrequestreview-1382842287). So it would be interesting to know about your use case.

The time in rally.log is different to host time, which just makes reading log inconvenient.  
It seems complex to support configuable timezone in rally.

This is now part of Rally 2.8.0. Thanks!
