windows clock sync.

what's going on with windows clock, I've been trying to adjust it for a long time and it doesn't work.moreover I had to disable sync, because windows tried to sync and couldn't and still delayed the clock between 2 to 3 seconds.

note: pc is new 2 months of use.

a.st1.ntp.br	200.160.7.186 e 2001:12ff:0:7::186

c.st1.ntp.br	200.186.125.195
d.st1.ntp.br	200.20.186.76
a.ntp.br	200.160.0.8 e 2001:12ff::8
b.ntp.br	200.189.40.8
c.ntp.br	200.192.232.8
gps.ntp.br	200.160.7.193 e 2001:12ff:0:7::193

o que está acontecendo com o relógio do windows, estou tentando ajustar há muito tempo e não funciona.além disso, tive que desabilitar a sincronização, porque o Windows tentou sincronizar e não conseguiu e ainda atrasou o relógio entre 2 a 3 segundos.

Maybe the server is wrong, you can use Time.is - exact time, any time zone for comparison.
Either way, it said I had a bad time either, but after running Update Time, it reports OK now.

see the img, "time and date not updated!"

Open the BIOS > view time > modify as needed > reboot > check time with time.is

If there are time problems > find a flash drive that you can format ( > or = 8 GB) > create a bootable Ubuntu flash drive:
Create a bootable USB stick on Windows | Ubuntu

Boot the computer using Ubuntu:
List of PC brands with their corresponding hot-keys

Open firefox > open time.is

Compare the earlier time keeping with Windows to Ubuntu > report results with images

I find the time sync in Windows is quite dumb.

Few stuffs that I observe:
1. If the offset is quite significant it won't sync.
2. Set time zone automatically might not be accurate

So, what I did:
1. Usually I change the time manually first and the it will start to sync automatically.
2. I change the time server to somewhere closeby, the br.pool.ntp.org (for Brazil) might be good enough.
3. I off the Time Zone detection completely.
4. I set time via Control Panel, not via Win -> Settings


Hope that helps.
