The Canadian Security Association, CANASA, has issued a reminder that the start of Daylight Savings Time has been brought forward this year as detailed below:Daylight Savings Time begins (clocks move forward one hour): Sunday, March 11Daylight Savings Time end (clocks move back one hour): Sunday, November 4.The change could create problems with security systems, access control, CCTV and computer applications. CANASA is recommending that its members take appropriate steps to contact system manufacturers to obtain their recommended protocol. The U.S. has also changed its daylight savings time schedule, and manufacturers such as Honeywell are advising that building and other automated systems may need to be adjusted. The United States has also decided to change its daylight saving schedule. As in Canada, beginning this year, clocks must move ahead by an hour starting on the second Sunday of March rather than the first Sunday of April.
The new arrangement also means clocks have to be set back on the first Sunday of November instead of the last Sunday of October as they were previously scheduled.
