                Starting today, Redshift will be billed in one-second increments for on-demand clusters. Pricing is still listed on a per-hour basis, but bills are now calculated down to the second and show usage in decimal form.
Per-second billing is applicable to instances that are newly launched or already running in all AWS Regions. Please visit the Amazon Redshift pricing page for more information.
