@eirikbakke , previously, the driver connected with `client` timezone.
If we change the default the `TimeZone=GMT`, it might break applications that might have code like the following:

```
executeQuery("select now()::text")... getString(1)
```

The results would change if the driver silently alters the timezone.

Do you have any other suggestion other than "move the driver to TimeZone=GMT by default"?

I expect it might be workable if we support `TimeZone` connection parameter so the driver uses the value provided by the user. Then, if user configures `TimeZone=GMT`, it would be user to ensure the queries use `now()::text` properly.
