Right Time Zone, wrong time

Question

Right Time Zone, wrong time

Mohamed jihad bayali 1,136

Hello Team,

I hope you're doing fine,

I just set an ntp server for my client, and sync it sucessfully with the PDC emulator of the domain.

The sync is ok, the tests are good, i configure the correct timezone on the PDC, but it gives the incorrect date (1 hour less than the correct date), i tried to disable/enable the daylight saving time, but nothing change.

the time that i choose is Casablanca UTC +1, and i can't understand why i have this incorrect date.

As per my understanding, the NTP is delivering Time to the servers in UTC, and then based on the timezone configured on the clients machine, the time is calculated.

For my machine the timezone is correct (UTC+1) but the time on the machines is incorrect

Any ideas please?

Here is the output

PS C:\Windows\system32> Get-TimeZone

Id : Morocco Standard Time

DisplayName : (UTC+01:00) Casablanca

StandardName : Morocco Standard Time

DaylightName : Morocco Daylight Time

BaseUtcOffset : 00:00:00

SupportsDaylightSavingTime : True

Everything seems to be alright + when i configure this timezone on the ntp server, i have the right time, the issue is only on the client sides.
Any ideas please?

You could try;

w32tm /unregister
net stop w32time
w32tm /register
net start w32time
w32tm /config /syncfromflags:domhier /update
net stop w32time
net start w32time

Then check again.

Hello dave,

i will check this with the customer next wednesday and i will give you feedback , thanks.

the commands that you sent will just uneegistrr the ntp on the client machine, and will force it again to synch with the dc right ?

i believe that the issue is related to the windows, maybe it’s missing some updates and the times zones configured are old or smtg like this, anyway i will test and will give you feedback.

if you have some other ideas or querirs, please feel free to share them with me thank you again

Hello there,

To work around this issue so that the NTP client is enabled to sync with the NTP server after a SPIKE state, configure Windows Time to use the MinPollInterval/MaxPollInterval as the polling interval.

An NTP client computer that is running Windows Server editions or Windows Client editions may not correct the time if the following conditions are true:

The NTP client syncs its time with the manually specified NTP server.

The NTP client uses SpecialPollInterval as a polling interval.

The time offset between the NTP client and the NTP server is greater than the LargePhaseOffset as configured in the NTP client.

In this situation, the NTP client cannot correct its time even after waiting for SpikeWatchPeriod to pass.

https://learn.microsoft.com/en-us/troubleshoot/windows-server/identity/specialpollinterval-polling-interval-time-service-not-correct

Hope this resolves your Query !!

For me it correct the time (Minutes and secondes are correct, and other timezones like Paris,Amsterdam..are correct too).
I have an issue only with Casablanca UTC+1 timezone

Look at this :

On my personal laptop (Timezone = casablanca and time displayed is correct) :

Basically it says "Daylight Saving time will end in 10 march 2024"

And for the domain computer (Timezone = casablanca, and time displayed in incorrect) here is what i got :

It says that Daylight savingn time will begin on 28 mayo (Which incorrect, as DST time began earlier in casablanca timezone).

I'm thinking of some missing windows updates, what do you guys think?
