	# In github actions get_redis.sh has modification time set when cloned but redis-server binary has modification
	# time when it was cached (always older than clone). By updating timestamp we avoid unnecessary build.
	# Cache key includes get_redis.sh file hash so there is no risk of using stale binary.
