Hello group
I ve browsed a lot of Google resources ans MSDN reference for GetTimeZoneInformation
but i still have not a clue about the values i am getting for StandardDate and DaylightDate.
thank you in advance for any help or information. i may be missing something obvious.

I get for StandardDate:

wDay = 3
wDayOfWeek = 5
wHour = 0
wMilliseconds = 0
wMinute = 0
wMonth = 0
wSecond = 0
wYear = 10

I get for DayLightDate:

wDay = 0
wDayOfWeek = 0
wHour = 0
wMilliseconds = 0
wMinute = -60
wMonth = 2
wSecond = -1
wYear = 5

And here is my code :

Private Declare Function GetTimeZoneInformation Lib "kernel32" _
(lpTimeZoneInformation As TIME_ZONE_INFORMATION) As Long

Private Type SYSTEMTIME
   wYear As Integer
   wMonth As Integer
   wDayOfWeek As Integer
   wDay As Integer
   wHour As Integer
   wMinute As Integer
   wSecond As Integer
   wMilliseconds As Integer

End Type

Private Type TIME_ZONE_INFORMATION
   Bias As Long
   StandardName(32) As Integer
   StandardDate As SYSTEMTIME
   StandardBias As Long
   DaylightName(32) As Integer
   DaylightDate As SYSTEMTIME
   DaylightBias As Long

End Type
Private Sub Form_Load()

Dim st As SYSTEMTIME
Dim tzi As TIME_ZONE_INFORMATION
Dim ret As Long

ret = GetTimeZoneInformation(tzi)
st = tzi.StandardDate

MsgBox st.wDay
MsgBox st.wDayOfWeek
MsgBox st.wHour
MsgBox st.wMilliseconds
MsgBox st.wMinute
MsgBox st.wMonth
MsgBox st.wSecond
MsgBox st.wYear

st = tzi.DaylightDate

MsgBox st.wDay
MsgBox st.wDayOfWeek
MsgBox st.wHour
MsgBox st.wMilliseconds
MsgBox st.wMinute
MsgBox st.wMonth
MsgBox st.wSecond
MsgBox st.wYear

End Sub
