Computer Clock Persistently Wrong and Slow

It nearly catches up to the right time and then gets 'knocked' back again . Currently its saying 11.09
But the time is now 12.05 according to my handed ticking clock.

Its been this way for several days , with some variation in it's time handling , as above .

What's going on with my computers clock ? Can anyone shed some on this as it's inconvenient at best , possibly a liability .
Does it suggest comprise of my hardware , or something more simple

I keep my handed clock a couple of minutes fast

Oh my goodness it now says 12.05

Cmos battery is the usual cause
Perhaps this post would be better in the computer forum?

Or....is the handed clock wrong?

No it's correct . The issue has resolved itself within the time I made this thread , and my isp has just reset my connection , which kicked me from the site , to an update page . I shut the page an re-enterd the site

Took the words right out my mouth.
Another thing to check first is to make sure that the time zone is correct and that your PC is not going back to another backup point due to a virus.

But most likely it’s your CMOS. Easy fix just make sure you clean that bad boy when you open it. Stay grounded and if you know how add some oil to those fans. And if it’s been a very long time maybe change the CPU thermal paste.

Sorry didn’t mean to get off topic. Every time I open mine I do all those besides the thermal paste as I have replaces that a few years ago.

I thought somehow that the clock system would be a basic set up , could you explain how its supposed towork please?
Something about how digital timekeeping is governed?

CMOS is only used to store time when the system is powered down. If that was the cause you would also lose all BIOS settings and that doesn't sound like that is happening here. You don't mention which operating system you use but most modern OS's use NTP (Network Time Protocol) to see what time it is. Maybe you have made changes to that setting. My modem and my ISP (Internet Service Provider) both provide NTP services to PC's on the network. If the time skew is more than 5 minutes, Windows (from version 7 at least) will refuse to perform a WIndows update. Good luck.

There is a software and a hardware side to your pc's clock.

First, the hardware: a battery supports the CMOS on it's job to store and advance the time and date.
Low battery = slower advancement of time and date.
Battery dead = CMOS empty = "where are my harddisks? What time is it? How much memory do I have?" (your computer).

Software side: depends on your OS. A newer Microsoft Windows? Should get its time and date from the internet based on your settings for "local region". Linux? Same. MacOS? I guess the same. It even might try to set that up in your computer's CMOS-memory. Just the problem that the low battery can not provide enough power for the CMOS to store and advance time and date accordingly..

Solution: Buy a new 2032-battery (or equivalent in your country, just look at the shiny round object on your motherboard, diameter about 0.8 inch or 20 milimeters)

Check which time server that the Operating System is connecting to to update time.
CMOS battery failure would only occur after a power down , unplug and power on
Yet , then it would reset to some wild , crazy date and time such as 1970 or 2022

The system would still feed the 3.3 volts or so.

Thanks everyone for the input , but it's doing it again !

Ive got back tonight and its now reading 17.16

When the time is actually 19 . 05

The date is correct

I'll try what's been suggested or drop into a computer shop if no joy

try changing your time from automatic to manual
set the city, set the time, set the date and see what happens
perhaps the time server you are using is not being contacted properly
