Timestamp issue with Hypnos

[garysekhon09]

Having issues with the timestamp while logging data with SD using Hypnos.
I tried to reset it by taking the coin cell battery out but it still not synching with the current time.

#define _dout A0 //MISO
#define _sclk A1 //SCK
#define _pdwn A2 //A2

#define sdPin 11 // Change to 11 if using HypnosV3.3
#define alarmPin 12 // Hypnos interrupt pin

#include "ADS1232.h"
#include "RTClib.h"
#include <SD.h>

ADS1232 weight = ADS1232(_pdwn, _sclk, _dout);
File myFile;
RTC_DS3231 rtc;

const float startingWeight = 815.00; // Known weight to divide by in grams
int unit = 0; // Units: {0 = grams, 1 = kilograms, 2 = ounces}
char buff[] = "Start time is hh:mm:ss DDD, DD MMM YYYY";

int packet = 0; // Packet number

void do_calibration() {
long t_new_offset = 0;
long t_raw_read = 0;
float t_set_scale_value = 0;
float t_weight = 0;

// reset to default values
weight.OFFSET = 0;
weight.SCALE = 1.0;

// tare
t_new_offset = weight.raw_read(100); // Takes 8 measurements and averages it
weight.OFFSET = t_new_offset;
Serial.print("Calibration offset = ");Serial.println(weight.OFFSET);
Serial.println("You have 15 seconds to put a known weight on the scale");
delay(15000);

// do calibration based on a known weight
t_raw_read = weight.raw_read(3);
Serial.print("Units read = ");Serial.println(t_raw_read);
t_set_scale_value = t_raw_read / startingWeight; // divide it to a known weight
weight.SCALE = t_set_scale_value;
Serial.print("Calibration scale value = ");Serial.println(weight.SCALE);

/*
// Force Calibrate
weight.OFFSET = 8521423; // Set to "Calibration offset" from calibration (8527704)
weight.SCALE = 2069.49; // Set to "Calibration Scale value" from calibration (427.06) */

// read weight
t_weight = weight.units_read(3);

// following line sets the RTC to the date & time this sketch was compiled
rtc.adjust(DateTime(F(DATE), F(TIME)));
// This line sets the RTC with an explicit date & time, for example to set
// January 21, 2014 at 3am you would call:

DateTime now = rtc.now(); // Get current time

// Print current time and date
