Thanks, done that.  It's right (Eastern US time).  I got the notice yesterday of Daylight Savings Time but the clock was exactly a HALF HOUR slow!  One hour forward and half back!!

 

Double check to see that you have the correct time zone set.

You didn't say what OS you're using, but XP has a time auto-set feature that you may want to turn off, if using XP.

Sorry, I'm running Win98 SE.  I'm not so hung up on the exact time, it's this sporadic EXACT error of 30 minutes that's driving me nuts.  I figure out what might be doing it.  I'm aware of the battery problems as machines and batteries age, I suspect this could be related to that issue.  But, I've never heard of a constant precise quantum shift of 30 minutes.  It doesn't sound like a battery just running down.

 

What model of system. How old. Software can cause this. Norton AV running? Usually this only slows your clock by a couple of minutes but anything is possible.

If this happens frequently, try disabling any programs at startup that you don't need for a test period.  Of course, be very careful letting down your virus defenses.

Hope this halps you

 

I had another thought for you, however it will require you leaving your system running for a test period and or starting it up in dos mode till you isolate your issue

When you are done using your system for the day, restart it in dos mode. Make sure the time is correct at a dos prompt by typing time at the prompt when the time displays just hit enter to keep it the same. At this point, you can leave the system running in dos mode overnight and try the command in the morning. See if the time lags. The other option is to shut down the system and let it sit overnight. the next day start the system in dos mode only. do not let windows load. run the time command again and verify if the time is correct. This will isolate things like a weak battery or some wierd system board problem and will prove that an interraction with windows or other software may or may be to blame.

Take care

Gozzi.

 Go to World Time Server  http://www.worldtimeserver.com/  and download Atomic Clock Sync, which is free. When you run this program, it will query the atomic clock at the National Institute of Standards and Technology. If the difference is more than 15 seconds, it will automatically adjust your system’s clock. In the Control Panel, open the Date and Time icon. Then, click the tab marked Internet Time and be sure there is a check mark before "Automatically synchronize with an Internet time server."

I've used the above with good results for over years.

Thanks all for some good ideas.  I'm in the process of trying several of them!  The computer of concern is my home Dimension.  It is internet linked only about 15 minutes per day (I've got the oldest phone lines in the city, so it's very slow and I'm spoiled with free high speed linkage at work so the home computer is fairly isolated).  (This also means that the background links to the Atomic clock will work fine here at work but less well at home.)  I will often leave the home system on over night (although modem is shut down).  Norton is running full time AND I will often put my Dell Axim in a synched cradle over night. At first I thought this to be a strong candidate for the cause.  But, Saturday at 415PM I synched the Axim and removed it from the cradle.  At that time the times matched perfectly; the PC, the Axim both with my trusty Timex.  At 730AM Sunday the Axim was still unconnected, had corrected for DayLight Savings and  matched the Timex.  The PC however indicated that it had corrected for DLS but it read exactly 30 behind the other two.  My assumption was that the PDA synch was not the cause of the shift since the shift occured while the Axim was not linked at all.
