Sukhoi:
I would be glad to give you a possible explanantion to your particular problem, since as an elite member you probably are a mature intelligent person who can have a rational dialogue with someone trying to answer your question.
"I just love to tell people (who usually are both shocked and delighted at the answer) that computers make absolutely terrible timepieces out of necessity and, as a result, that time display in the lower right-hand corner of the Windows screen lies like a rug.
There is a great way to compensate for the fact that your $1,500 AMD-Pentium howler lacks the time sense of a $3 kiddies' special watch at Walmart.
There is ample information about the issue and an atomic clock at
www.worldtimeserver.com. The free Atomic Clock Sync software that one can download will check with the U.S. Naval Observatory's ultra-accurate atomic clock and reset yours to match.
The reason that PCs come with cheap clocks stems from the fact that computers operate by performing the maximum possible number of operations during each cycle of an internal clock. These cycles are measured in megahertz. If the computer had to check and reset the time of day during each of those clock cycles, the CPU "speed" would be dramatically slower, and so PCs always have come with inexpensive crystal timepieces tacked on to the circuit board.
Worse, since the computer only checks the time roughly every second, (thru the bios) the time that gets displayed always lags the time on the cheap crystal. Over time these small discrepancies become ever greater.
No matter how expensive and powerful your PC is, it always will tell the time of day worse than even the cheapest wristwatches and clocks.
So the first no money way to check out your prob is to reference your PC to the atomic clock. Going to the store and getting a few batteries and trying them would be your next $5 solution, and as the battery runs down the time losses become greater (you did not specify losses)
Even if you dont need the batteries, every computer person should have a few on hand anyway. I recently bought an A7V266-E motherboard from Newegg and the battery was 1.498 (half expended)
out of the box. While the board was new - remember that THEY (ASUS) also buy their batteries from someone else, and batteries have shelf life.
On a bit more technical note you may note this:
PCs keep time in two ways: using a hardware and a software clock. The hardware clock, referred to as the RTC (real-time clock), uses your system's battery to keep time when your PC is off. When your PC is on, the software clock takes over. It sets itself to the hardware clock, and from then on, it keeps time based on the rate of interrupt requests from your system's BIOS (Basic Input/Output System).
But neither the hardware clock nor the software clock is more accurate than a cheap digital wristwatch. The RTC doesn't actually stay close to real-time and can gain or lose up to 10 seconds per day. And a software clock is usually less accurate because the frequency of interrupt requests varies, depending on how hard your computer works, how long it stays on, and the ambient room temperature. A software clock can gain or lose up to a minute a day.
Abnormalities in your home or office electrical system might affect the frequency of interrupt requests and cause inaccuracies in your software clock.
A strong power spike (such as from a lightning strike) or dip in power (called a brownout) might RESET your BIOS and RTC and could ruin your PC. To guard against power surges (periodic voltage increases), plug your PC into an effective surge protector. For protection against power spikes and brownouts, use a UPS (uninterruptible power supply). I think this is the wimp helpless pussy's actual problem.
If your computer keeps time relatively well when it's on but loses time while it's turned off, then your BIOS battery is probably..
