[nfbcs] Computer Clock

Some computers sync up their clocks with networks, but I've never found computer clocks to be 
particularly more accurate than other clocks.  Being five minutes fast over time doesn't seem like it 
means a hardware problem, and the possibility of synchronizing to a network that is fast also seems like 
a possibility.  I would think resetting the time through the operating system and observing whether the 
time stays accurate for a while or becomes inaccurate at a specific point would make sense.  I also 
don't know that a low battery always means that the time will be slow.  Lowering the voltage does not 
always mean that an oscillator's frequency will drop, they can be inversely proportional depending upon 
the circuit.  If the computer is old, like several years or more, replacing the battery is probably 
worth trying if this is a recurring problem even if the clock is fast.  There are also some programs out 
there that will synchronize time to various sources and this might be a workaround even if the clock is 
somewhat defective.

Best regards,

Steve Jacobson
