hmmm... on MSDN

I haven't found any info about a SYSTEMTIME structure filled with
zero's. In fact, it's true with all Windows version, but not under
Vista. MSDN talk about dwFlags only.

IMHO Borland IsBlankSysTime() is a useless function... with this patch
in CNNotify(), control seems to works correctly

    else begin
      if FShowCheckbox and (dwFlags = GDT_NONE) then  {patch}
      // if FShowCheckbox and IsBlankSysTime(st) then {original}
    FChecked := False
      else if dwFlags = GDT_VALID then
      begin
