I have a [standard install](https://meta.discourse.org/t/142537?silent=true) that I just upgraded that is failing due to a timezone issue. I think that it may be just one user, but I’m not quite sure yet.

It was for just one user. When I went to his profile his time zone was not set. When I set the time zone the issue went away.

EDIT: maybe he had his timezone set to that bogus value? I tried another user with a nil timezone and there was no error.
