Starting today, Amazon RDS is billed in one-second increments for database instances and attached storage in AWS China (Beijing) region operated by Sinnet and AWS China (Ningxia) region operated by NWCD for on-demand instances and 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. There is a 10 minute minimum charge when an instance is created, restored or started. Per-second billing is applicable to instances that are newly launched or already running.

Please visit the Amazon RDS pricing page for more information on per-second billing for all applicable AWS Regions.
