Sorry for the top post and lack of snipping this email down, I'm using a mobile phone.
Can you explain why the system clock gets so far out of time? I certainly struggle with crime (time?) drifting even on an always network connected machine, but I'm not understanding why your machine can not maintain time within a very small margin of error even if turned off for months. Over time the crystal that controls the system clock will degrade. So it will oscillate at slightly different frequencies and affect the clock. The less expensive systems seem to degrade faster, as will a system that gets hot often. No simple electronic circuit can be totally accurate, it would be too expensive.
