Summary: RtlSetTimeZoneInformation() incorrectly calls
                    settimeofday()
           Product: Wine
           Version: unspecified
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: test
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

the RtlSetTimeZoneInformation() function in dlls/ntdll/time.c fails to do
anything because it calls settimeofday() with a NULL first parameter

gcc/glibc warns about this:
time.c:1059: warning: null argument where non-null required (argument 1)

and indeed the glibc code basically does:
if (tv == NULL) return -1;
