    Hello @Manjot Singh ,

    Thank you for posting here.

    1.Would you please tell us whether your Windows server 2019 is in one domain or not?
    2.Is your Windows server 2019 virtual machine or physical machine?

    If your your Windows server 2019 is in one domain, we can see Time Synchronization in an AD DS Hierarchy.

    1.Time on PDC is synchronized with external NTP time server.
    2.TIme on other DCs is synchronized with PDC.
    3.Time on domain clients and member servers is synchronized with other DCs.

    Registry configuration method

    ===PDC===

    (If PDC is a virtual machine, set the first one entry, if PDC is not a virtual machine, don’t set this one entry)

    HLM\SYSTEM\CurrentControlSet\services\w32time\TimeProviders\VMICTimeProvider
    Name: Enabled
    Type: REG_DWORD
    Data:0

    Path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config
    Key Name: AnnounceFlags
    Type: REG_DWORD (DWORD Value )
    Data: 0x5

    Path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\Type
    Key Name: Type
    Type: REG_SZ(String Value)
    Data: NTP

    Path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters
    Key Name: NtpServer
    Type: REG_SZ(String Value)
    Data: Peers （time.windows.com,0x9）

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpServer
    Key Name: Enabled
    Type: REG_DWORD
    Data: 1

    ===other DC & Client===

    Path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\Type
    Key Name: Type
    Type: REG_SZ(String Value)
    Data: NT5DS

    Path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config
    Key Name: AnnounceFlags
    Type: REG_DWORD (DWORD Value )
    Data: 0xa

    GPO configuration methond

    If your Windows server 2019 is not in any one domain, we can configure it as below.

    Path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\Type
    Key Name: Type
    Type: REG_SZ(String Value)
    Data: NTP

    Path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters
    Key Name: NtpServer
    Type: REG_SZ(String Value)
    Data: 0.ca.pool.ntp.org

    Tip: Please back up your registry first before changing it.

    Hope the information above is helpful.

    Should you have any question or concern, please feel free to let us know.

    Best Regards,
    Daisy Zhou
