If roundtripping to other version control systems is an argument, adding sub-second timestamps could potentially create as many problems as it solves. For example, I've been using the hg-git bridge, and it supports roundtripping between git and mercurial today (for most repos I've tried anyway). I may have missed something, but this could imply that mercurial doesn't care about sub-second timestamps either. If so, and if git suddenly were to record it, it would no longer be as straight forward to represent git history in hg. In my opinion it would be a shame to sacrifice this compatibility just to reduce the distance to svn, which is much larger anyway. - Thomas -- 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
