I purchased the Sony ICF - C218 clock radio as a replacement for one I already had I had the first one for over 15 years. I did not have to worry about changing the time for daylight savings time. It automatically did it. If the power went out in the middle of the night, I did not have to worry about being late for work. The alarm went off at the right time. After 15 years I noticed that a minute was added to the time after every power outage. It was well over time for a new alarm clock. I had no second thoughts about purchasing another Sony ICF - C218.
