Prema zadanim postavkama Windows 11/10/8/7 sinkronizira vrijeme vašeg sustava s internetskim^(Internet) poslužiteljima na tjednoj bazi. Ako želite ručno sinkronizirati i ažurirati vrijeme svog sustava s poslužiteljem internetskog vremena^{(Internet Time)} kao što je time.windows,com , morate desnom tipkom miša kliknuti na Vrijeme^(Time) na programskoj traci > Adjust Time i datum > kartica Internet vrijeme ^{(Internet Time)}> Change postavke > Update sada .

Promijenite Windows Internet Time Update Interval

Ali što ako želite sinkronizirati svoje vrijeme automatski, s poslužiteljima češće – recimo svakodnevno? Možda imate svoje razloge zašto to želite promijeniti na svakodnevno – ili čak na mjesečnu! Da vidimo kako to možete učiniti. Prije nego što nastavimo, naučimo nekoliko stvari o tome kako sinkronizacija vremena radi u sustavu Windows^(Windows) .

Windows Time Service – W32Time.exe

The Windows Time Service or W32Time.exe maintains date and time synchronization on all clients and servers in the network. If this service is stopped, date and time synchronization will be unavailable. If this service is disabled, any services that explicitly depend on it will fail to start.

Mnogi unosi registra za uslugu ^(Registry)Windows Time isti su kao i istoimena postavka pravila grupe . ^{(Group Policy)}Postavke pravila grupe^{(Group Policy)} odgovaraju unosima u registar istog imena koji se nalaze u:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\

Windows Time Service Tool – W32tm.exe

W32tm.exe ili Windows Time Service Tool mogu se koristiti za konfiguriranje postavki Windows Time Service . Također se može koristiti za dijagnosticiranje problema s vremenskom uslugom. W32tm.exe je preferirani alat naredbenog retka za konfiguriranje, praćenje ili rješavanje problema s uslugom Windows Time . TechNet baca više svjetla na ovo.

Da biste koristili ovaj alat, morat ćete otvoriti povišeni naredbeni redak^{(elevated command prompt)} , upišite W32tm /?i pritisnite Enter da biste dobili popis svih njegovih parametara. Kada se pokrene w32tm /resync , on govori računalu da odmah sinkronizira svoj sat. Kada sam pokrenuo ovu naredbu dobio sam sljedeću pogrešku: Usluga nije pokrenuta^{(The service has not been started)} . Dakle, Windows Time usluga^{(Windows Time service)} mora biti pokrenuta da bi ovo funkcioniralo.

1] Korištenje Planera zadataka

Sada kada biste kreirali zadatak koristeći Task Scheduler , za pokretanje Windows Time Service i ove naredbe za sinkronizaciju na dnevnoj bazi, kao Lokalni servis^{(Local Service)} s najvišim privilegijama, mogli biste natjerati svoje Windows računalo da sinkronizira vrijeme vašeg sustava svaki dan.

Morat ćete otvoriti Task Scheduler i ići na Task Scheduler Library > Microsoft > Windows > Time Synchronization . Sada ćete morati kliknuti na vezu Kreiraj zadatak...^{(Create Task…)} da biste stvorili zadatak. Ovaj post će vam detaljno reći  kako zakazati zadatak pomoću Planera zadataka^{(how to schedule a task using Task Scheduler)} .

Pod Akcije^(Actions) biste morali odabrati Pokreni program ^{(Start a program)} %windir%\system32\sc.exe s argumentima start w32time task_started . To će osigurati da Windows Time usluga radi. Zatim možete postaviti drugu radnju na Pokretanje programa ^{(Start a program)} %windir%\system32\w32tm.exe s argumentom  /resync . Ostale postavke možete odabrati prema svojim osobnim preferencijama.

SAVJET : ^(TIP)Vremensku zonu^{(Time Zone)} možete promijeniti i pomoću tzutil.exe .

2] Korištenje uređivača registra

Također možete vidjeti radi li ovo za vas. Otvorite Windows Registry Editor i idite do sljedećeg ključa registra:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet\Services \W32Time\TimeProviders\NtpClient

Odaberite SpecialPollInterval.

This SpecialPollInterval entry specifies the special poll interval in seconds for manual peers. When the SpecialInterval 0x1 flag is enabled, W32Time uses this poll interval instead of a poll interval determined by the operating system. The default value on domain members is 3600.

Zadana vrijednost na samostalnim klijentima i poslužiteljima je 604.800 . 604800 sekundi je 7 dana. Stoga ovu decimalnu vrijednost^{(decimal value)} možete promijeniti na 86400 da bi se sinkronizirala svaka 24 sata.

There is also the easy way out!

Ovaj besplatni alat s DougKnox.com omogućuje vam promjenu intervala ažuriranja internetskog vremena^{(Internet Time Update)} iz tjedno^(Weekly) u dnevno^(Daily) ili po satu^(Hourly) . Morat ćete pokrenuti alat kao administrator.

Ovaj prijenosni alat radi na sustavima Windows XP^{(Windows XP)} , Windows Vista , Windows 7 i Windows 8 . Nije provjereno radi li na Windows 11/10 .

Pročitajte^(Read) : Provjerite točnost vašeg sistemskog sata^{(Check the accuracy of your system clock)} .

Ovaj će vam post pomoći ako vaša sinkronizacija vremena^{(Time Synchronization)} ne uspije s pogreškom – Windows Time Service ne radi^{(Windows Time Service not working)(Windows Time Service not working)} .

Change Internet Time Update interval in Windows 11/10

By default Windows 11/10/8/7 syncѕ your system time with Internet ѕervers on a weekly basis. If you want to manually sync аnd update your syѕtem time with an Internet Time server like time.windows,com, you have to right-click on the Time in the taskbar > Adjust Time & date > Internet Time tab > Change settings > Update now.

Change Windows Internet Time Update Interval

But what if you want to sync your time automatically, with the servers more frequently – like say daily? You may have your reasons for wanting to change this to daily – or even on a monthly basis! Let us see how you can do it. Before we proceed, let’s learn a few things about how Time synchronization works on Windows.

Windows Time Service – W32Time.exe

The Windows Time Service or W32Time.exe maintains date and time synchronization on all clients and servers in the network. If this service is stopped, date and time synchronization will be unavailable. If this service is disabled, any services that explicitly depend on it will fail to start.

Many Registry entries for the Windows Time service are the same as the Group Policy setting of the same name. The Group Policy settings correspond to the registry entries of the same name located in:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\

Windows Time Service Tool – W32tm.exe

W32tm.exe or the Windows Time Service Tool can be used to configure Windows Time Service settings. It can also be used to diagnose problems with the time service. W32tm.exe is the preferred command-line tool for configuring, monitoring, or troubleshooting the Windows Time service. TechNet throws more light on this.

To use this tool, you will have to open an elevated command prompt, type W32tm /? and hit Enter to get the list of all its parameters. When w32tm /resync is run, it tells the computer to synchronize its clock right away. When I ran this command I received the following error: The service has not been started. So the Windows Time service has to be started for this to work.

1] Using  Task Scheduler

Now if you were to create a task using the Task Scheduler, to run the Windows Time Service and this sync command on a daily basis, as a Local Service with highest privileges, you would be able to make your Windows computer synchronize your system time every day.

You will have to open the Task Scheduler and navigate to Task Scheduler Library > Microsoft > Windows > Time Synchronization. Now you will have to click on the Create Task… link to create the task. This post will tell you in detail how to schedule a task using Task Scheduler.

Under Actions, you would have to choose Start a program %windir%\system32\sc.exe with arguments start w32time task_started. This will ensure that the Windows Time service is running. You may then set the second action to Start a program %windir%\system32\w32tm.exe with the argument  /resync. The other settings you may choose as per your personal preferences.

TIP: You can also change Time Zone with tzutil.exe.

2] Using Registry Editor

You can also see if this works for you. Open Windows Registry Editor and navigate to the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet\Services \W32Time\TimeProviders\NtpClient

Select SpecialPollInterval.

This SpecialPollInterval entry specifies the special poll interval in seconds for manual peers. When the SpecialInterval 0x1 flag is enabled, W32Time uses this poll interval instead of a poll interval determined by the operating system. The default value on domain members is 3600.

The default value on stand-alone clients and servers is 604,800. 604800 seconds is 7 days. So you may change this decimal value to 86400 to make it sync every 24 hours.

There is also the easy way out!

This freeware tool from DougKnox.com lets you change the Internet Time Update interval from Weekly to Daily or Hourly. You will have to run the tool as an administrator.

This portable tool works on Windows XP, Windows Vista, Windows 7 & Windows 8. Not checked if it works on Windows 11/10.

Read: Check the accuracy of your system clock.

This post will help you if your Time Synchronization fails with the error – Windows Time Service not working.
