I get a weird error message when I boot up the computer

Question

Every once in a while when I boot up my computer it gives me an error message that says:
"Your computer’s clock is set to a date before March 24th 2001. This may cause some applications to behave erratically."
But my clock is not set to an old date/time. And when I go into the date/time settings to check, they are always set correctly. Why am I getting this message??

Answer 1

it could be logic board problem (just a guess at this point and not a conclusion), unless some software setting changes date/time as was suggested.
logic board is the main electronic board inside, containing processor, video chip etc., it also includes the chip controlling real time and date.
it is possible that the time chip is failing for some reason and it can't be replaced on it's own - the whole board may need to be replaced.
if the iBook is out of warranty it will be to expensive and probably not worthwhile just for the clock problem.
if it's in warranty (1 year from purchase date or 3 years with AppleCare warranty) any authorized service provider will get it fixed:

you can look up the warranty here by entering serial number for the iBook where it says "About Your Support Coverage":

also someone may have other suggestions on software causes.
