Did you re-check the "automatic update" function in Date & Time?

Also, check that the Mac "knows" where you are, in the world. It may thing it has moved back to its birthplace! eek2.gif

Bad battery contacts. Try cleaning them with a pencil eraser.
Bad charging circuit. With the Mac ON, there should be a low current DC voltage on the contacts.
Bad battery (they can get old/die just sitting on the dealers shelf). Check its voltage, under a load, if possible. If it's more than 1 volt low, ask for another. Take your meter with you to the shop and see what a 'new' one reads.
Bad plist (/System/Library/PreferencePanes). You can try renaming this, but the OS may not let you. If it does, it will probably want your login password (whether you ever use it or not).
Bad cacheTimeZones cache ( /System/Library/CoreServices). Probably best not to mess with this one...Thinking.gif

Always a good trick is to look through the Crash logs. In your Utilities folder should be an app called Console. I think it's pronounced cun•sole, as it's meant to make you think you will find something in there that will help you find a problem process. Sometimes it does...I'd look at "system.log, /Library/Logs and ~/Library/Logs" at least, then "CrashReporter" (although this is not really a 'crash'). Look in the lists for anything even vaguely involved wit date/time. Report any findings in triplicate, pink to Admins, blue to your dad, gray for your own records. salute.gif

Good luck, this message will self-destruct in 5 seconds...4...3...2...1 scram.gif

That would properly refer to the change in the battery but it depends on where in the log you found this. Was it on the day and time when you changed the battery? If so, it makes sense. If it is in a recent log, then something else is going on.

When you say the clock doesn't keep correct time, exactly how off is it? By an hour, so many minutes, etc.  If exactly a certain number of hours then it appears your location settings may be off as ABD explained.  If it loses a few minutes or odd amounts, then it is possible you have a bad battery or it's not installed correctly. Are you sure it was put in with the + and - ends in the right place?. Could Dad have purchased from someplace that might have stuff sitting on the shelf for long periods of time?

i think this entry was the day after the battery was changed
[attachment=1419:Picture_4.png]
  this entry appeared today.
the clock keeps in time if synchronizes with the interweb. if i uncheck the box and disconnect power then it loses time rapidly. i left it without power for 8 hrs and it slipped back into 1970! which was a good year for me, all that disco pop music and flared trousers!
i am fairly sure that george bought the battery from a reputable dealer and have double checked the installation.

Good trouble-shooting by Paddy! clap.gif It sounds like it is definitely the battery, see below.

I'm willing to bet the battery will show very little voltage, if any, after the machine has been off for some time. As soon as you turn it on, it will start powering the charger, so checking after a longer period of time may indicate some voltage. The reason for the low voltage (assuming that is the case) could be one of several reasons. My suspicion is that it was not charged enough when it was bought and it may not be able to be charged past that 'on-the-shelf' voltage. Ni-Cads are especially bad about doing that. The more costly reason could be that the internal power supply is not completely functional.

Either way, until the fix is in, you'll probably continue to get those warnings. I'll see if there is a way to make them go to George's Mac, instead of yours. wink.gif rofl.gif
