Yes, it can be corrected.  There are ways of offsetting NTP to allow for 
clocks which are more than 500 ppm off nominal.  Likely it's 
OS-dependant, but for Windows I documented the method here:

I would certainly agree that if the clock is more than 500 ppm out it 
should be investigated and possibly replaced!
