> "Leading up to the 2015 leap second event, there was concern within the financial industry that similar issues could lead to a disruption to trading operations across exchanges, clearinghouses, brokers, investors and key service providers. The Commodity Futures Trading Commission asked U.S. futures exchanges to provide details on how they planned to approach the leap second event. Some exchanges published plans to delay the opening of trading. Several exchanges in Asia have also announced details regarding how their systems will adjust their clocks before or after the leap second, and will retain normal trading hours."
