Windows API Guide: GetLogicalDriveStrings Function

---

Declare Function GetTimeZoneInformation Lib "kernel32.dll" (lpTimeZoneInformation As TIME_ZONE_INFORMATION) As Long

Platforms: Win 95/98, Win NT

GetTimeZoneInformation reads the computer's current time zone settings. Since Windows handles all of the system clock settings, there usually isn't a need for other programs to use this information. The information is put into the variable passed as lpTimeZoneInformation. The function returns 0 if an error occured, or a 1 if successful.

lpTimeZoneInformation

Variable which receives the information about the system time zone.

Example:

' Display the name of the time zone the computer is set to. Dim tzi As TIME_ZONE_INFORMATION  ' receives information on the time zone Dim retval As Long  ' return value Dim c As Long  ' counter variable needed to display time zone name retval = GetTimeZoneInformation(tzi)  ' read information on the computer's selected time zone ' Oddly, instead of being stored in a string, the time zone name is stored in a ' 32-element array, each element holding the ASCII code of one of the characters. ' This loop converts the array into a readable string. Debug.Print "The computer's time zone is: "; For c = 0 To 31  ' the array's range is from 0 to 31   If tzi.StandardName(c) = 0 Then Exit For  ' abort if the terminating null character is reached   Debug.Print Chr(tzi.StandardName(c))  ' convert the ASCII code into a character and display it Next c Debug.Print ""  ' end the line being displayed
