[solved]setting date on mega and wiznet

ok, now it is answering after this:
include <Wire.h>
#include <Rtc_Pcf8563.h>
#define I2C_RTC 0x51

//init the real time clock
Rtc_Pcf8563 rtc;

void setup()
{
Serial.begin( 9600 );
//clear out the registers
rtc.initClock();
//set a time to start with.
//day, weekday, month, century(1=1900, 0=2000), year(0-99)
rtc.setDate(15, 4, 11, 0, 12);
//hr, min, sec
rtc.setTime(21, 52, 0);
}

void loop()
{
//both format functions call the internal getTime() so that the
//formatted strings are at the current time/date.
Serial.print(rtc.formatTime());
Serial.print("\r\n");
Serial.print(rtc.formatDate());
Serial.print("\r\n");
delay(1000);
}

but still have wrong values back:

45:85:85
