在Windows XP上更改时区xp

您好，我正在尝试更改windows xp上的时区，并且我正在关注此guide。我正在使用C++，似乎没有设置适当的特权标志。下面是代码：在Windows XP上更改时区xp

TIME_ZONE_INFORMATION tzInfo, tzInfoNew, tzInfoTest; 
DWORD dwRet; 

HANDLE hToken; 
TOKEN_PRIVILEGES tkp; 

OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES|TOKEN_QUERY, &hToken); 
LookupPrivilegeValue(NULL, SE_SYSTEMTIME_NAME , &tkp.Privileges[0].Luid); 
tkp.PrivilegeCount = 1; 
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED; 
AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, (PTOKEN_PRIVILEGES)NULL, 0); 

dwRet = GetTimeZoneInformation(&tzInfo); 
std::wcout << "STANDARD NAME: " << tzInfo.StandardName << std::endl; 

tzInfoNew.Bias = tzInfo.Bias + 60; 
StringCchCopy(tzInfoNew.StandardName, 32, L"Nikola Time Zone"); 
tzInfoNew.StandardDate.wMonth = 10; 
tzInfoNew.StandardDate.wDayOfWeek = 0; 
tzInfoNew.StandardDate.wDay = 5; 
tzInfoNew.StandardDate.wHour = 2; 

StringCchCopy(tzInfoNew.DaylightName, 32, L"Nikola Daylight Zone"); 
tzInfoNew.DaylightDate.wMonth = 4; 
tzInfoNew.DaylightDate.wDayOfWeek = 0; 
tzInfoNew.DaylightDate.wDay = 1; 
tzInfoNew.DaylightDate.wHour = 2; 
tzInfoNew.DaylightBias = -60; 


if(!SetTimeZoneInformation(&tzInfoNew)) 
{ 
    printf("STZI failed (%d)\n", GetLastError()); 
} 
dwRet = GetTimeZoneInformation(&tzInfoTest); 
std::wcout << "STANDARD NEW NAME: " << tzInfoTest.StandardName << std::endl; 
std::wcout << "STANDARD NEW DAYLIGHT NAME: " << tzInfoTest.DaylightName << std::endl; 

tkp.Privileges[0].Attributes = 0; 
AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, (PTOKEN_PRIVILEGES) NULL, 0);

编辑：我已经插入这个方法在我的项目，我有一些奇怪的问题。反正我现在用的是以下结构：

typedef struct { 
    unsigned short month; 
    unsigned short week; 
    unsigned short day; 
} dstDate; 

typedef struct { 
    unsigned short hour; 
    unsigned short minute; 
    unsigned short second; 
} dstTime;

这里是整个方法一起：

bool::setTimeZone(short int timeZone, short int dstOffset, dstDate& sDate, dstTime& sTime, dstDate& eDate, dstTime& eTime){ 
    bool res = true; 

    TIME_ZONE_INFORMATION tzInfoNew; 

    HANDLE hToken; 
    TOKEN_PRIVILEGES tkp; 

    // Get the necessary priviledge to perform time zone setting operation 
    OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES|TOKEN_QUERY, &hToken); 
    LookupPrivilegeValue(NULL, SE_SYSTEMTIME_NAME , &tkp.Privileges[0].Luid); 
    tkp.PrivilegeCount = 1; 
    tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED; 
    AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, (PTOKEN_PRIVILEGES)NULL, 0); 

    // Fill the TIME_ZONE_INFORMATION structure 
    ZeroMemory(&tzInfoNew, sizeof(tzInfoNew)); 
    tzInfoNew.Bias = (LONG) -timeZone; 

    // Start of DST 
    // If the following six lines are executed, then setting the time zone fails 
    // i.e. it goes with result status 0, but the time zone is not changed 
    tzInfoNew.DaylightDate.wMonth = sDate.month; 
    tzInfoNew.DaylightDate.wDayOfWeek = sDate.week; 
    tzInfoNew.DaylightDate.wDay = sDate.day; 
    tzInfoNew.DaylightDate.wHour = sTime.hour; 
    tzInfoNew.DaylightDate.wMinute = sTime.minute; 
    tzInfoNew.DaylightBias = dstOffset; 

    // End of DST 
    tzInfoNew.StandardDate.wMonth = eDate.month; 
    tzInfoNew.StandardDate.wDayOfWeek = eDate.week; 
    tzInfoNew.StandardDate.wDay = eDate.day; 
    tzInfoNew.StandardDate.wHour = eTime.hour; 
    tzInfoNew.StandardDate.wMinute = eTime.minute; 

    if(!SetTimeZoneInformation(&tzInfoNew)) { 
    printf("STZI failed (%d)\n", GetLastError()); 
    res = false; 
    } 

    tkp.Privileges[0].Attributes = 0; 
    AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, (PTOKEN_PRIVILEGES) NULL, 0); 

    return (res); 
}

所以SetTimeZoneInformation返回状态OK，但时区未设置。只有在设置了DaylightDate信息时才会出现问题，否则就没关系。

什么是错误值？ [documentation]（http://msdn.microsoft.com/en-us/library/windows/desktop/ms724944%28v=vs.85%29.aspx）指出：“一个应用程序必须具有此函数的SE_TIME_ZONE_NAME特权才能成功。“还有一些示例代码。 –

SE_TIME_ZONE_NAME自Windows Vista开始实施，因此您无法将其用于XP。该文档指出，对于XP SE_SYSTEMTIME_NAME需要使用。没有错误cuz函数返回0.但是，当我稍后检索时区信息时，它表明时区未更改 – nikolakoco

您是对的，我错过了XP注释，对此抱歉。 –

在设置任何数据之前，我发现了问题，我没有在TimeZoneInformation结构中使用ZeroMemory宏。

ZeroMemory(&tzInfoNew, sizeof(tzInfoNew)); 
tzInfoNew.Bias = 0; 
StringCchCopy(tzInfoNew.StandardName, 32, L"Test Time Zone"); 
.....

我认为这是无关紧要的使用它。但它做到了，我不太清楚为什么，因为我已经设置了所有必要的信息，并且在设置时区时结构已满。

很高兴你知道了。它看起来像'StandardBias'，SYSTEMTIME'结构中的一些变量没有被初始化，并且基于填充它的复杂规则，你几乎保证了一个奇怪的冲突。 –

是的你是对的，但它让我困惑，没有任何错误代码 – nikolakoco

现在有一个新问题，请参阅问题的编辑部分。 – nikolakoco
