"Bash" is frequently a codeword for "assumes GNU shell utilities".
At first glance it actually looks like a POSIX sh script without
overt bashisms.

At least this will need adapting; presumably we align with "Darwin"
here:

  FDATE='date +%Y-%m-%d -r'
  [ "$system" = "Darwin" ] && FDATE='stat -f %Sm -t %Y-%m-%d'

I did _not_ read the whole thing closely.
