Please also remove this from your > documentation patch. Well... I couldn't resist another little change that has been nagging me for a while. Both the author and committer time stamps are very closely related most of the time. So the committer time stamp is now encoded as a difference against the author time stamp with the LSB indicating a negative difference. On git.git this saves 0.3% on the pack size. Not much, but still impressive for only a time stamp. Nicolas
