change the commit time of a bunch of commits at once

[bernd]

This might be interesting for others too ... I really like clean commit history. Thus I like to have no mixed commit dates, and I do not like to have commit dates far away from now in the past. Thus sometimes I set them before going for a merge:

Code: Select all

git filter-branch -f --env-filter \
    'export GIT_AUTHOR_DATE="$now"
     export GIT_COMMITTER_DATE="$now"
     sleep 2s' \
     --tag-name-filter cat -- commitHashFromCommitOneBeforeStartToSet..HEAD

#

example:

Code: Select all

$ git filter-branch -f --env-filter \
>     'export GIT_AUTHOR_DATE="$now"
>      export GIT_COMMITTER_DATE="$now"
>      sleep 2s' \
>      --tag-name-filter cat -- 50f91840d6..HEAD

Ahh do not forge git filter-branch can mess up your whole git reopository. Just in case ... you have been warned
