Answer / Rajesh Kumar Sahu
To get a list of valid time zones in Windows using Delphi, you can utilize the TRegistry class. Here's a simple example:nn```delphinprocedure GetTimeZones(const RegPath: string; var Zones: TStringList);nvarn Key, Value: string;n I: Integer;nbeginn Registry.OpenKey(HKEY_LOCAL_MACHINE, RegPath, Key);n Zones := TStringList.Create;n for I := 0 to Key.NumberOfValues - 1 don beginn Key.GetValueName(I, Value);n if (Value = 'TZI') thenn Zones.Add(Key.OpenSubKey(Value).GetValue('DisplayName').StringValue);n end;nend;nn// Usage:nvar TimeZones: TStringList;nGetTimeZones('SYSTEMCurrentControlSetControlTimeZoneInformation', TimeZones);n```
