What I find strange is that the threads never mix. B comes
after A and when B finishes then comes C.

I would expect something like:
  14:37:01.984 thread_A start job
  14:37:01.984 thread_B start job
  14:37:01.984 thread_C start job
  14:37:01.984 thread_A finish job
  14:37:01.984 thread_C finish job
  14:37:01.984 thread_B finish job

On my computer it is mostly 0.010

Did compare it with GetTickCount() and results are the same.

Try:

   mylogfile->Write( FormatDateTime("hh:nn:ss.zzz", Now() )
	+ "  " + IntToStr ( GetTickCount() ));

I just did following test:

void __fastcall TForm1::Button1Click(TObject *Sender)
{
   TStringList *StringList = new TStringList;

   int times = 0;

   while ( ++times < 5000 )
    StringList->Add ( FormatDateTime("hh:nn:ss.zzz", Now() )
	 "  " + IntToStr ( GetTickCount() ));

   Memo1->Text = StringList->Text;

   delete StringList;
}

So your threads are logging to fast!
