This is to guard against the possibility that multiple processes have a different timestamp output dir name, due to one or more of the processes being slower than rank 0 and reaching the timestamp-generation line later than rank 0.

When the `--output-folder-name` flag is used there's no possibility of
the different processes having a different output folder name, this
value is only able to be different for different processes when
generating a timestamp. Hence, the broadcast is only done for the case
of an automatically generated timestamp output folder name.
