git skew: a tool to find how big a clock skew exists in the history
> As you probably guessed from the specificity of the number, I wrote a > short program to actually traverse and find the worst skew. It takes > about 5 seconds to run (unsurprisingly, since it is doing the same full > traversal that we end up doing in the above numbers).

This patch doesn't implement auto-detection of skew, but is the program I used to calculate, and would provide the basis for such auto-detection. It would be interesting to see average skew numbers for popular repositories. You can run it as "git skew --all".
