Wrong time on some client machines (-1 hour)

Question

Wednesday, March 28, 2018 7:08 AM | 1 vote

Hello,

We have some strange problem with time (-1 hour) on some windows 10 (also 7 pro) clients. We have domain controller, so all machines are syncing time from it.

I've seen, that "automatically adjust clock for daylight saving" option is not enabled - when I enabled it manually on some client, the time were OK, so I've created a GPO for it.

I've created reg item: DynamicDaylightTimeDisabled and set it to "0". And here's the problem, because all machines have the option automatically adjust clock for daylight saving enabled... but the "faulty" clients still have -1 hour. If I reenable this option manually the clock have proper time.

Hi DW.mayr,

Hello,

Yes, timezone is the same both on DC and "faulty" clients.

Hello,

Have you checked if CMOS battery (usually coin-like battery) has enough power.

Sorry, I cannot say more than this.
Please refer to the following article:

Hello,

If the DC is a server, Please Disable Time Sync from  VM host(Hyper-V or VMWare)

Follow up below steps and configure time server again and, Restart the server and check the status,

** **

1.       Run cmd as administrator, then execute below command.

 

w32tm /config /manualpeerlist:"time.windows.com yourtimeserver.com" /syncfromflags:manual /reliable:yes /update

 

2.       Then Stop, Unregister, Register and Restart time service

 

Stop-Service w32time

w32tm /unregister
w32tm /register

Start-Service w32time

 

3.       Check Status

 

w32tm /query /status

 

4.       Enable logging

 

w32tm /debug /enable /file:C:\w32tmdebug.log /size:10485760 /entries:0-300

 

5.       Turn Off Log

 

w32tm /debug /disable

 

6.       Allow UDP port 123 in Firewall

ECHO Querying DNS

Portqry -n %logfile% -p both -e 123 > 123.txt

refer below website to select correct time server based on your Zone,

It only occurs some end clients, not the DC itself.

I've replaced CMOS battery on one "faulty" PC (the 2nd "faulty" PC is a new one, no need to replace), and set proper time in the BIOS. After 1st windows boot - time were OK, but after restart it was -1 again.

Hi DW.mayr,

Sorry for so late reply.
How is your issue? Has it been resolved?

You have already checked/modified GPO, summer time, CMOS battery. I can imagine nothing beyond those. If you resolved the issue, please provide how to. It will be helpful for those who have the same issue.

I was having the same problem while setting up a friend's computer. I think it may be a glitch. I selected Eastern time with adjust for daylight savings time selected when I set it up, but it was
-one hour. The correct time zone was also displayed on the Date & Time settings page, but when I checked the additional settings, Central time was selected. Here's what worked for me:

Go to additional date and time settings (Settings>Time & Language>Date & Time, scroll down to Related Settings, Select "Additional Date, Time & Regional Settings" and under "Date & Time" select "change time zone" and click on the appropriate time zone. Hit ok and the time should change.

Good luck.
