The "-40643156" timezone definitely looks suspicious, though. I'm > curious if it is bad handling in the time code, or if the commit has > corrupt ident lines. Actually, I just noticed in your earlier message a link to the public GitHub repository. So to answer my own questions: $ git cat-file commit 23c07cc | egrep '^author|committer' author Sean D'Epagnier <seandepagnier@xxxxxxxxx> 5758122296 -40643156 committer Sean D'Epagnier <seandepagnier@xxxxxxxxx> 5758122296 -40643156 Yes, the timezone really is that ridiculous value. No, the author and committer aren't different. According to GNU date, the correct timestamp is actually in 2152. Offhand, I'd guess that the timestamp exceeding 2^32 is getting converted somewhere inside git to a bogus value, and that's how we end up with 2106. -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
