The API seems to return a float for the time, but at least as far I can see, it never has any decimals anyway. But it doesn't really matter, mercurial doesn't have a committer information either. This is solved by tools like hg-git by storing the information in an 'extra' field, which can store anything. Unfortunately git doesn't have a similar field, so people have been using the commit message to store extra information. Either way, I don't see the point in changing git's commit format for external tools. The git-notes functionality works just fine for that, it just needs to be attached in the relevant places, like 'git fast-export'. BTW. Have you checked git's native support for hg?[1] Cheers.
