To fix invalid timezone info in a repo I ran git filter-branch --env-filter ' GIT_AUTHOR_DATE=`echo ${GIT_AUTHOR_DATE}|sed s/+0000/-0800/`' HEAD This fixed the invalid entries but the new timezone is -0700 instead of -0800. Is this expected? git version 1.7.4.rc2 -- 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
