CMOS Battery Wierdness?

I've had boxes run for years and I don't think I've ever had to change a
battery but a software application I am using is writing to the database and
time stamping 6 hours later than my system time which by appearances remains
correct and stable.

I would think a tired battery would cause time to lag behind rather than
stamping a date 6 hours into the future and the fact that my system time
remains correct and stable has me puzzled. So I thought I'd ask if anybody
has ever observed this kind of anomaly that may suggest changing the
battery?

This can occur in MS O/S around the time of year when the clocks go
back(It did to me).Sometimes and for whatever reason the internal code
of the O/S doesn't update correctly several times.

Use a free Sync program a couple of times over the next couple of
days,should clear it,

I've been synchronizing the system clock to time.windows.com -- maybe
they're the problem ;-) --. I would have thought synchronization would
resolve this issue but I appreciate your comments and will try your
suggestion Shep.

a weak battery can do add things...
i;ve had a few machines not even boot up at all when the battery voltage
was about 1.6 volts

GMT????? Could it be that they use a standard time rather than a local one?

I think you have an interesting supposition Ken. Thanks for bringing it to
my attention as I had not even considered an offset.

My system time is -6 GMT (Central Time) and the application is recording 6
hours into the future. I'll set my system time back by 8 hours and see if
the timestamp remains consistent.

You make my point for me philo as I can't see how a weak battery can allow
the system time to remain consistent, even after running synchronization and
most interesting is the fact that the timestamp is 6 hours into the future
whereas a weak battery would lose time.

If it was a mechanical clock, yes. If it was a digital clock, not
necessarily. You do not have a "mechanism" of gears and a motor to slow
down when your battery runs down, instead, things just start generally
misbehaving and dropping in and out of function.

Good point but the consistent offset 6 hours into the future still has me
puzzeld. Come Monday I'm going to pick up a new battery and see what
happens.

Philo it did it to me just a couple of weeks ago on this time
change-over(Yet another MS bug) and I don't got a weak batteries.As
mentioned before I use ,"MY" PC to re-charge some of my 2032 batteries
for one of those small fat reducing belts I got cheap.In my case it's
not for the fat but it helps with a muscle problem I have as and yes
you,"Can" re-charge lithium 2032 batteries :D

I've got several here that are well over 3 years old in various
devices(Not all PCs).

Note:Duracell are not only top brand by name but they really
do,"Last-the-Distance" and re-charge great :D

Now that sparks an idea -- a USB powered batyery charger.
