Bug ID: 53610
           Summary: NtSetSystemTime not allowed: difference -930 ms
           Product: Wine
           Version: 7.16
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

It looks like since mid-2020, NtSetSystemTime has been a stub that does nothing
except possibly error when the difference is not greater than -500ms and less
than 500ms.

In the past, wine used to call settimeofday when NtSetSystemTime was
implemented directly in dlls/ntdll/time.c, but this is seemingly no longer
present in dlls/ntdll/unix/sync.c.

Is this intentional? Unfortunately, it's causing a time syncing feature to fail
for a server daemon that I use, which I can't distribute.

The call to NtSetSystemTime is from SetLocalTime(const SYSTEMTIME *).
