> The following tests tend to fail when using test-with-docker. What's common
> about them is that they're doing a time zone conversion.

> It turns out that people parse {{readlink(/etc/localtime)}} to find out the
> current time zone. This got noticeable when the ORC change landed (though
> I've seen that one come and go) and then very frequently when we changed time
> zone DBs. (Or so I think.)
> I have a simple change forthcoming.
