Record turns up with hilariously inaccurate date

This item:

```
        "id":"111148262015/vNvo7NxhQkAbckOYFxFGug==",
        "source_file":"BL-293667154-20150211114826-00001-safari.bl.uk.warc.gz",
        "source_file_offset":440,
```

Must have something odd in the WARC, because the crawl date is `1114-12-26T20:15:00Z`.

It's not open access, unfortunately, so I can't post the WARC here.
