if I change my code in this mode, and change Google Calendar configuration,
with Greenwich meridian, I see correct result on Google Calendar. But I'm
not on Greenwich meridian.
I edited the demo calendar. I added a button and inside I put the following
code.
procedure TMainForm.Button1Click(Sender: TObject);
var
Entry : TEvent;
Insert : TEvent;
start_e : TEventDateTime;
end_e : TEventDateTime;
begin
if LBCalendars.ItemIndex<0 then
Exit;
start_e := TEventDateTime.Create();
end_e := TEventDateTime.Create();
start_e.dateTime := EncodeDateTime(2020,6,3,19,0,0,0);
start_e.timeZone := 'Europe/London';
end_e.dateTime := IncHour(start_e.dateTime,2);
end_e.timeZone := 'Europe/London';
Entry := TEvent.Create();
Entry.summary := 'My test';
Entry.description := 'My test';
Entry.location := 'My location';
Entry.start := start_e;
Entry._end := end_e;
Entry.guestsCanInviteOthers := false;
Entry.guestsCanSeeOtherGuests := false;
Entry.colorId := '';
Insert := FCalendarAPI.EventsResource.Insert(FCurrentCalendar.id,Entry);
SaveRefreshToken;
Entry.Free;
Entry:=nil;
ShowMessage('Insert ' + Insert.id);
Insert.Free;
Insert:=nil;
end;
