This value is stored in the file index to allow 'got status' to skip
expensive content comparison for files which did not see an mtime
change since the last time they were visited. It does not serve any
other purpose and is not exposed to the repository.

I think localtime makes sense here since it will match the values
displayed by stat(1) and ls(1).
