community suggested fix: CVEProject/cvelistV5#130

There might be a cleaner way to solve the issue with some fs.statSync calls.

Or if going with env var, you could use last time a git-pull was attempted
last_local_cache_pull=$(stat -c %y $(git rev-parse --show-toplevel)/.git/FETCH_HEAD)

• get root of git repo: git rev-parse --show-toplevel
• get FETCH_HEAD of current git repo: $(git rev-parse --show-toplevel)/.git/FETCH_HEAD)
• get time of last data modification of a file (human-readable): stat -c %y <filepath>

%y time of last data modification, human-readable
