I'm running into this same issue. Note that `.astimezone()` can provide access to the local timezone: ```python >>> datetime.datetime.now().astimezone().tzinfo datetime.timezone(datetime.timedelta(days=-1, seconds=72000), 'Eastern Daylight Time') ```

Actually, it's probably best to just use the old code in the `except` block: ```python except Exception as exc: from sphinx.buildert.gettext import timestamp, ltz ctime = datetime.datetime.fromtimestamp(timestamp, ltz).strftime('%Y-%m-%d %H:%M%z') ```

I had the same "sector not found" issue with dumpkeysector, decrypt, and dumplast on MacOS Sierra. ``` # reallymine dumplast /dev/disk5 dumplast0627.out error running dumplast: non-empty sector not found ```...
