source:

git-cache-time              Works like git-cache-meta but only store file timestamp

git-cache-meta --store      Cache all meta include numeric uid/gid/permission in .git_cache_meta
git-cache-meta -f           Alias of --store

git-cache-meta --stdout     Same as --store but output in console
git-cache-meta -c           Alias of --stdout

destination:

git-cache-meta              Works like git-cache-meta but only store file timestamp
                            but restore "all" the meta in .git_cache_meta
                            
git-cache-meta --apply      Apply/Restore meta saved in .git_cache_meta
git-cache-meta -r           Alias of --apply
