How about using the Win API function

DWORD GetTimeZoneInformation(
LPTIME_ZONE_INFORMATION lpTimeZoneInformation);

where lpTimeZoneInformation points to a TIME_ZONE_INFORMATION struct:

typedef struct _TIME_ZONE_INFORMATION { // tzi
    LONG       Bias;
    WCHAR      StandardName[ 32 ];
    SYSTEMTIME StandardDate;
    LONG       StandardBias;
    WCHAR      DaylightName[ 32 ];
    SYSTEMTIME DaylightDate;
    LONG       DaylightBias;
} TIME_ZONE_INFORMATION;

Where Bias is the differance between the local time and the Coordinated 
Universal Time (UTC).
StandardDate Specifies a SYSTEMTIME structure that contains a date and UTC 
when the transition from daylight time to standard time occurs on this 
operating system. And vice versa for DaylightDate. I assume that by standard 
time and daylight time they mean winter time and summer time.
SYSTEMTIME looks like this:

typedef struct _SYSTEMTIME {  // st
    WORD wYear;
    WORD wMonth;
    WORD wDayOfWeek;
    WORD wDay;
    WORD wHour;
    WORD wMinute;
    WORD wSecond;
    WORD wMilliseconds;
} SYSTEMTIME;
