Altering Commit Dates

$ (export GIT_COMMITTER_DATE="1970-01-01 00:00:00"; \
        git commit --amend --date="$GIT_COMMITTER_DATE")

(The parentheses spawn a subshell, which is required for the environment variable to take effect.)

$ git log --format="%h [%cd] %ad %s"

This reveals both commit and authoring dates.
