mergerfs.balance retain timestamp

[no1knows]

I've just run a mergerfs.balance across five disks and it appears not to have retained the timestamp on the moved files. I'd have expected the default would be to do this (using rsync -t ?). Am I missing something?

-a, --archive archive mode; equals -rlptgoD (no -H,-A,-X)
