What is the difference between windows time and windows time (w32time) in windows?


Asked by Jensen Tran on Dec 14, 2021 Windows



Windows Time is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the Windows Time service is started, it is running as NT AUTHORITY\LocalService in a shared process of svchost.exe along with other services.
Moreover,
The Windows Time service (W32Time) synchronizes the date and time for all computers managed by Active Directory Domain Services (AD DS). This article covers the different tools and settings used to manage the Windows Time service. By default, a computer that is joined to a domain synchronizes time through a domain hierarchy of time sources.
Besides, Applies to: Windows Server 2022, Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2012, Windows 10 The Windows Time service (W32Time) synchronizes the date and time for all computers managed by Active Directory Domain Services (AD DS).
Consequently,
By default the Windows Time service ( w32time) will synchronize it's time once per week. This can be extended to daily by setting a Scheduled Task to start the service and run w32tm /resync.
Thereof,
The hierarchy revolves around the Primary Domain Controller (PDC) or a DC with the root forest, or a DC with a Good Time Server for the Domain (GTIMESERV) flag. Standalone computers use the time.windows.com service.
