The --ttl flag specifies the time-to-live (TTL) for the token. In this case, it is set to ${12h0m0s}. The 12h0m0s represents a duration of 12 hours. You can use different units to define the duration, such as hours (h), minutes (m), or seconds (s). So, ${12h0m0s} means the token will be valid for 12 hours.
Overall, this command generates a new authentication token for accessing a Kubernetes cluster and sets its validity duration to 12 hours.
