Nova Scotians are reminded to set their clocks back one hour on Sunday, Nov. 7, when daylight savings ends at 2 a.m., or before going to bed Saturday evening. Along with watches and clocks, microwave ovens, VCR and DVD players, answering machines, car clocks and automatic timer lights need to be adjusted. It is also a reminder to change batteries in smoke detectors and carbon monoxide detectors. Smoke alarms should be tested monthly and replaced every 10 years. People are also advised to check computer calendars to ensure appointments are up to date when the time change occurs.
