New Daylight Savings Time Begins March 11, Institutions Need To Check Systems
Daylight Savings Time (DST) in the United States will begin earlier and end later in 2007. The Energy Policy Act of 2005, signed into law August 2005, moves the beginning of DST from the first Sunday in April to the second Sunday in March (March 11). DST will now end the first Sunday in November (November 4) instead of the last Sunday in October.
The OCC bulletin noted institutions should include this change in their risk management considerations. The bulletin noted, â€œThe impact of the change in DST may not cause systems failures, but without remediation and preparation, institutions could experience logging errors, monitoring difficulties, degraded system performance, or disruptions of some services. In addition, malfunctioning systems could result in compliance errors (e.g., incorrect ATM disclosures) and securities issues (e.g., malfunctioning security systems).â€
It continued, â€œManagement should understand the potential impact of the DST change on its hardware and software and plan for appropriate changes. Servers, mainframes, other important systems, and essential computer clock-dependent processes should be set to synchronize with the new time change. Management should review both date and time stamp processes and the many time-sensitive routines essential to information systems.â€
The OCC also recommended major operating system vendors should have suitable patches available for the most current releases of their systems. Vendors of other systems and applications may also have patches available. â€œIf, however, no patch is currently available, management should confirm that its vendors will provide a suitable patch. Internally developed or customized systems may require custom patches or other special attention. Whether suitable patches are available or not, management should develop and implement strategies to appropriately mitigate risks associated with this time change.â€
Other systems may be affected as well; for example, those controlling heating, air conditioning, lights, alarms, telephone systems, and the opening of cash vault doors. If third parties provide time-sensitive services, management should ensure that the servicers are planning to make appropriate changes, the OCC bulletin noted.
The OCC recommended management should consider the following actions to ensure readiness for the new start of DST:
â€¢ Review and verify modifications necessary for all important systems and essential processes, including servers, applications, and utility systems.
â€¢ Ensure that critical systems will synchronize and function properly by testing or other means.
â€¢ Determine which systems are connected to the USNO Master (Atomic) Clock through a network time protocol (NTP or NTPD) and whether they will synchronize with the master clock at the appropriate moment.
â€¢ Contact third-party service providers to ensure that the institution is protected.
â€¢ Determine whether the institution has systems that require a manual procedure to be performed and whether a follow-up plan is needed.
â€¢ Ensure that systems adjustments will not be duplicated when the historic change date occurs.
â€¢ Ensure that all employees throughout the institution are alerted to this change.
According to the CUNA article, older versions of Microsoft operating systems will not make the change to the new time automatically. Microsoft has instructions on how to manually update home and office operating systems on its website.
