This is because when we read the date from the author script file is already prefixed by '@' so we do not need to add one. This did not show up in our tests because once match_object_header_date() fails to match because of the extra '@' parse_date_basic() strips the prefix and a date with more than 8 digits is parsed as a number of seconds by match_digit(). While fixing this I also noticed that we were not setting GIT_COMMITTER_DATE in the environment when forking `git merge`. This was untested. The tests we did have used commits where the author date was the same as the current value $GIT_COMMITTER_DATE in the environment so they did not test that we were actually using the author date when creating the commit. As we have already read GIT_AUTHOR_DATE into cmd.env_array we now use that rather than re-reading the author-script file. I've moved the code that handles opts->ignore date so that all the code setting the child environment is together and changed it so we no longer set GIT_COMMITTER_DATE twice when --ignore-date is combined with --committer-date-is-author-date.
