my sytem need to display time and date in the second line.

In a 16x2 LCD no, but you can try this fucnction it is quite efficient:

void ScrollMessage(unsigned char row,const char Message[])
{
 char TempS[21];
 unsigned int  MHead=0,Done=0,counter;
 if(row >1) row=1;
 row=row*40;
 while(Done==0)
 {
  for(counter=0;counter<16;counter++)
  {
	  TempS[counter]=Message[MHead+counter];
	  if(Message[MHead+counter+1]==0) Done=1;
	 }
	 MHead++;
  lcd_goto(row);
  lcd_puts(TempS);
  DelayMs(SCROLLDELAY);
  DelayMs(SCROLLDELAY);
 }
}

LCM i think is a Liquid Crystal Module, Its the name given to an LCD with a control circuit.
