[fpc-pascal] Is TryStrToDate works wrong?

[Gabor Boros]

Hi All,

var
  DT:TDateTime;

begin
  Writeln(BoolToStr(TryStrToDate('1',DT),True));


The result of above code is "True" with FPC and "False" with Delphi.

This is normal. FPC accepts more than Delphi, see the documentation:

Hi!


The result is true, but the date is nonsense:

ShowMessage(BoolToStr(TryStrToDate('1',DT),True) + lineEnding + 
formatdatetime('dd.mm.',DT));


results in

/True//
/

/01.01.2020/


Not what I exspected.

But exactly what it is supposed to return. It fills missing numbers with the
current year/month. So, 1 jan 2020.
