FINRA Requests Comment on a Proposal to Tighten Business Clock Synchronization Requirements

Comment Period Expires: Friday, January 9, 2015


Executive Summary

FINRA is soliciting comment on a proposal to reduce the synchronization tolerance for computer clocks. The current clock synchronization requirements allow for a tolerance of one second from the National Institute of Standards and Technology (NIST) atomic clock. Under the proposal, the tolerance for computer clocks would be reduced to 50 milliseconds. The tolerance for mechanical time stamping devices would remain at one second.


The proposed rule text is set forth in Attachment A.
