About 11 000 revisions on the Chinese Wikisource have timestamps from January 1970 (which seems like a Unix epoch bug) and January 2001. [Rev 254184](https://zh.wikisource.org/w/index.php?diff=254184) and [rev 187693](https://zh.wikisource.org/w/index.php?diff=187693) are representative. The rev_ids of these revisions all seem to be six digits, suggesting that they were actually made in 2008 or later.
As best I can tell, the wiki was created [around November 2003](https://zh.wikisource.org/w/index.php?diff=174). Chinese Wikisource seems to be the //only// wiki with this kind of weird timestamping in the revision table

SELECT LEFT(rev_timestamp, 6) AS month, rev_user_text, rev_user, COUNT(*)
