Hmm, this might not stop a system clock from losing time. The software fix is a better solution. I recommend to all my clients to leave their computers on all the time. Less wear on the parts all the way around.
i can confirm that I reset the clock before the open then after a few hours it's already one or two seconds behind .
I think this isn't the complete story. If turning your computer on and off reduced its life expectancy by 50% and it normally lasts 10 years -- is anyone going to use a 5 year old computer? If, on the other hand, your computer is drawing 100 watts an hour to operate and you turn it off for 12 hours each day, you are saving over 1.2 kilowatt/hours a day, or roughly half a megawatt/hour a year. At an average cost of 12 cents per kilowatt hour, you are saving around $60 a year on electricity.
An average of $5 per month in bill savings? I'spose. I was speaking more so to reducing the increased possibility of hard drive failure based on cycling the power on/off.
