Update:
 Well it seems that the time is anywhere from 2 minutes to 13 minutes off. However it seems to reset itself periodically.

Is there a program I can put in to help keep this as close to the right time as possible?

Update: Just did a reboot to my system because the time was off by 10 minutes.
Had let the system run for 4 days. Lost the time over that many days.

Update: as of today the time is now 22 minutes ahead of what it is supposed to be and the computer has been running for 5d 3:21
Why is this happening?
Thanks

I'm not sure why this happens.
Try this
Code: [Select]
sudo apt-get install gnome-time-admin ntpYou'll find 'Time and Date' in the Whisker menu. Open it and click on Unlock and it will ask you for a password. You should see 'Manual' option.
Switch it to the other option, something like 'Keep time synchronised with web servers'.
I hope this helps.

Hello Ohjrson,

I found this website http://linux.die.net/man/8/hwclock

It states "You can also run hwclock periodically to insert or remove time from the Hardware Clock to compensate for systematic drift (where the clock consistently gains or loses time at a certain rate if left to run)."

Systemic drift sounds like/similar to what you have described.

In the options area of the page it covers
Code: [Select]
-u
 --utc
--localtime

and states -
"If you specify the wrong one of these options (or specify neither and take a wrong default), both setting and querying of the Hardware Clock will be messed up. "

It may be worth looking into these on the link in more detail and altering these settings to see if any of these options solve the issue.

Reading a little more on this I notice -
"It works like this: hwclock keeps a file, /etc/adjtime, that keeps some historical information. This is called the adjtime file. "

So if this file is absent or not working for some reason then the hwclock will not check the current time and adjust the clock correctly, I am unsure how to test the adjtime file.
Finding this out would probably be better to test first before altering any of the options for hwclock.

Hi Ohjrson,

Does this laptop sometimes boot to Windows? I know one cause for out of sync time is booting between an OS on local time (usually Windows) and an OS on universal time (usually Linux).

~Scott

No it is exclusively LL 2.0 or Beryl.
Oddly enough now my laptop is having wireless issues... Go figure.
update: That issue was resolved and should be correctly marked.

As far as the time. I have left the computer on and it looks like I have lost 4 minutes since Monday.

I seem to be having the same issue I was having with LL 1.08 regarding losing time with LL 2.0 or Beryl.

I have done a hardware update with the NTP server and the time is correct now. I used what rokytnjl suggested on the code and it showed my hardware time was out of sync so with that synced up now I am hoping it will stay. I was hoping that I would not have this issue with LL 2.0 or Beryl. and the odd thing is I did the install for Beryl on my laptop and it seems fine. So go figure.

Good day,

Had a similar problem with my laptop after installing LL 2.0. Having tried online remedies to try to change system admin time (and restarting the machine many times) to no avail, I turned to synaptic. Found a prog called "gnome-time-admin". I set my time and date in there and have had no problems since.

Note: Only experienced this issue with the Laptop. Desktop kept Time and Date perfectly after LL 2.0 installation.

Ok N4RPS
   I have made a discovery of sorts I guess. I recently looked at my time on my Linux lite OS and it was off quite a bit. So as normal I went to the command prompt and did an update and low an behold it updated to the right time. SO..... the Bios is keeping the right time but the OS LL 1.08 is dropping off slowly for some reason. Now I still have the LL 1.08 on my laptop and it has no problem keeping time. So any idea's as to what may not be set right in the OS?

Thanks.

Hello!

Yes, that's what I'm saying.  Even though the capacitors are, in quantity, a few cents each, by the time you buy the many (and many different values of) electrolytic capacitors, and expend the effort to change them all, you approach the cost of a new motherboard.

Additionally, you don't know if it'll even work again after you've done all that, as changing certain components out affects others in ways you just can't predict...

Thanks N4RPS for the information.
AS it happens I have a little bit of electronics knowledge but not a lot. I knew that those little cans were capacitors but I did not know their full name, or that they are electrolytic. It just so happens I have a DVD recorder that won't power on at all now and when I took off the cover I saw that one of them had indeed blown. Odd thing is that it was on before and just would not come on again once I shut it off. The power board is separate from the rest of the system and is connected by ribbons and such to the other components. How difficult is it to replace those and would it be worth actually trying to or better/less expensive to try and order a replacement power board from the manufacturer.

As for the issue with the time slowly slipping away. it seems I am still having the issue, even aftger replacing the battery for the cmos. I am going to have to look into the power supply more closely to see if something similar has happened. But so I am clear you are saying that if those (capacitors) have any sign of bulging or blown then the mother board is no good and I should just get another one?

Let me know.
Thanks again.

Hello!

The CR2032 CMOS battery voltage is SUPPOSED to be 3.2 V. I'd change it. It could be producing a fairly decent voltage and, at the same time, not provide adequate current to properly run the oscillator.

After that, keep a watch on the system time in the BIOS, as well as in the OS. If it continues to change, and you're CERTAIN that your power supply's good (I'd change THAT, also, if you have a known good spare), then you most likely have a weak component in the oscillator portion of the real-time clock - most likely, a capacitor.

Some computers display the power supply voltages in the BIOS, but I use a special tester that cost me around $30, just to check power supplies. It gives me a digital display of both voltage and amperage for ALL the outputs.

Look at the electrolytic capacitors on the motherboard (they look like little cans). If the tops of ANY of them are bulging or have ruptured, then the motherboard is pretty much history. You could 'recap' it, but at that point, it'd be cheaper to buy (or scrounge) another old machine instead...
