Comment 5 for bug 1674195

> If 'local' doesn't work for some reason, we should tell the user and suggest they use "--timezone original" rather than silently ignoring their (explicit) preference.

In theory, but not practically. Do you really want an error message for 1 commit /1000 of your history and be forced to switch to 'original' for the 999 commits that you can show as 'local' without problem ?

> I don't follow why this causes out of range errors. What is the value of the t variable when you hit this issue?
