Consolidated Audit Trail (SEC Reg NMS)

The United States Security and Exchange Commission (SEC) has established new rules governing financial market information, commonly referred to as Regulation or Reg NMS (National Market System). Reg NMS includes requirements for the synchronization of clocks and maintaining related audit trail information. These are covered in paragraph (d) of 17 CFR 242.613 (Rule 613):

  • Clocks should be synchronized to NIST (National Institute of Standards and Technology) time.
  • Synchronization standards should be revaluated annually.
  • Clock granularity should at minimum be recorded/reported in milliseconds and possibly finer increments as required by NMS.

FINRA has well-established procedures and policies regarding time synchronization that allow you to address the Reg NMS requirement for "reasonable policies and procedures". We recommend you use our instructions on configuring for compliance with FINRA to ensure the clocks on your various systems are synchronized and generating correct time-stamps and are collecting the necessary audit trail records to satisfy your data retention requirements.
