Get Email Date/Time

Demonstrates getting the email "Date" header field in a CkDateTime object. Delphi DLL

var
success: Boolean;
email: HCkEmail;
dtTime: HCkDateTime;
bLocalTime: Boolean;
unixTime: Integer;
dtObj: HCkDtObj;

begin
success := False;

email := CkEmail_Create();

//  Load a .eml file into the email object.
success := CkEmail_LoadEml(email,'/home/users/chilkat/eml/myEml.eml');

dtTime := CkDateTime_Create();
CkDateTime_SetFromRfc822(dtTime,CkEmail__emailDateStr(email));

//  Once we have the CkDateTime object, we can get the date/time in many different formats:

//  Get as a RFC822 GMT string:
bLocalTime := False;
Memo1.Lines.Add(CkDateTime__getAsRfc822(dtTime,bLocalTime));

//  Get as an RFC822 string in the local timezone.
//  (remember, the daylight savings that existed at the given time in the past is applied)
bLocalTime := True;
Memo1.Lines.Add(CkDateTime__getAsRfc822(dtTime,bLocalTime));

//  Get as a 32-bit UNIX time (local or GMT..)
//  The Unix time is number of seconds since the Epoch, 1970-01-01 00:00:00 +0000 (UTC). 
unixTime := CkDateTime_GetAsUnixTime(dtTime,bLocalTime);
Memo1.Lines.Add('Unix time: ' + IntToStr(unixTime));

//  One can also get the as a "DtObj" object for accessing the individual
//  parts of the date/time, such as month, day, year, hour, minute, etc.
//  The DtObj can be obtained in the GMT or local timezone:
dtObj := CkDtObj_Create();
CkDateTime_ToDtObj(dtTime,bLocalTime,dtObj);

if (CkDateTime_getLastMethodSuccess(dtTime) = False) then
  begin
    Memo1.Lines.Add('This should never really happen!');
    Exit;
  end;

Memo1.Lines.Add(IntToStr(CkDtObj_getDay(dtObj)) + '-' + IntToStr(CkDtObj_getMonth(dtObj)) + '-' + IntToStr(CkDtObj_getYear(dtObj)) + ' ' + IntToStr(CkDtObj_getHour(dtObj))
     + ':' + IntToStr(CkDtObj_getMinute(dtObj)) + ':' + IntToStr(CkDtObj_getSecond(dtObj)));
