DateTimeToUnix 1 stunde zurück

[Klaus01]

in 10.4 sieht UnixToDateTime so aus:

Delphi-Quellcode:

function UnixToDateTime(const AValue: Int64; AReturnUTC: Boolean): TDateTime;
begin
  if AReturnUTC then
    Result := IncSecond(UnixDateDelta, AValue)
  else
    Result := TTimeZone.Local.ToLocalTime(IncSecond(UnixDateDelta, AValue));
end;

Da es TTimeZone in D2010 noch nicht gibt, muss dies wieder ersetzt werden.

Delphi-Quellcode:

function TzSpecificLocalTimeToSystemTime(lpTimeZoneInformation: PTimeZoneInformation; var lpLocalTime, lpUniversalTime: TSystemTime): BOOL; stdcall;
function SystemTimeToTzSpecificLocalTime(lpTimeZoneInformation: PTimeZoneInformation; var lpUniversalTime,lpLocalTime: TSystemTime): BOOL; stdcall;

implementation

function TzSpecificLocalTimeToSystemTime; external kernel32 name 'TzSpecificLocalTimeToSystemTime';
function SystemTimeToTzSpecificLocalTime; external kernel32 name 'SystemTimeToTzSpecificLocalTime';

Function UtcToLocalDateTime(d:TDateTime):TDateTime;
var
 TZI:TTimeZoneInformation;
 LocalTime, UniversalTime:TSystemTime;
begin
  GetTimeZoneInformation(tzi);
  DateTimeToSystemTime(d,UniversalTime);
  SystemTimeToTzSpecificLocalTime(@tzi,UniversalTime,LocalTime);
  Result := SystemTimeToDateTime(LocalTime);
end;

->>

Delphi-Quellcode:

function UnixToDateTime(const AValue: Int64; AReturnUTC: Boolean): TDateTime;
begin
  if AReturnUTC then
    Result := IncSecond(UnixDateDelta, AValue)
  else
    Result := UtcToLocalDateTime(IncSecond(UnixDateDelta, AValue));
end;
